make it unconditional
remove all definitions in the 'Configuration.h's
remove form 'Conditionals.h'

- Address issue #1669
- Remove the TOPO_ORIGIN configuration setting

- `Conditionals.h` is included twice, setting LCD values the first time

- Add `Conditionals.h` with calculated configuration values
- Add `SanityCheck.h` with checks for configuration errors
- Remove equivalent code from all configurations
- Move error checks from some sources to `SanityCheck.h` also
- Fix initialization of count_direction in stepper.cpp

- Addressing issue #1608

Added option to set Travel Acceleration (non printing moves).
The M204 options was a non sense (S for printing moves and T for retract
moves).

It has been changed to:
P = Printing moves
R = Retract only (no X, Y, Z) moves
T = Travel (non
printing) moves

I will add this info o G-Code wiki in reprap.org. I also advise to put
this info in Marlin next version changelog.

- Moved sanity-checks to Marlin_main.cpp
- Applied to other configuration files
- Fixed formatting of ABL output
- Passing verbose level to probe_pt
- Miscellaneous cleanup
- Put CONFIG_STEPPERS_TOSHIBA into Configuration.h

Looks like INVERT_E3_DIR was missing in the configuration.h also as I
did a test compile with 4 extruders and Azteeg X3 Pro defined. So I also
added those lines too. Additional formatting to make the comments line
up better in that section.

I've insert the define and pointer entries for the Viki 2 and miniViki
from Panucatt in all of the example configs and main config. With these
additions and with pins done in the old single pin.h style...I was able
to get the display working fine save for needing to turn Delta Segments
per Second down. But that's a common graphics lcd issue being looked
into right now.

I need assistance in understanding how the new divided pins files fit
together because my previous attempts at trying to get it to work
appropriately didn't seem successful. This originally came from trying
to find out how to swap the XYZ Min and Max Endstop pins in the Azteeg
X3 Pro. It only comes with one set of connectors and they're Min
Endstops. My previous experience didn't turn out well trying to tell the
firmware to home to the Min Endstops so the best solution I found was to
swap the pins in the firmware. If I'm missing a conflict with a setup
other than delta please let me know, but it makes sense in my setup.

Here were a few changes that I had to make/add lines for the 4th hotend.
A compiling problem in the Temperature.cpp and missing lines in
configuration.h and configuration_adv.h. I added these lines in all of
the example configs too.

Example Configuration.h: fixed strange white characters preventing
compilation in lines 1 and 3 - oops

Example Configuration.h for K8200 back in sync
* Configuration.h: rebased and added missing changes
* Configuration.h: updated comments for K8200

# Add: Example Configuration for Vellemann K8200 - based on new
BOARD_K8200 #1391

* K8200: new folder in example_configurations for Vellemann K8200 (3Drag
clone - should work with 3Drag http://reprap.org/wiki/3drag, too. Please
report)
* K8200/Configuration.h/Configuration_adv.h: updated manually with
parameters form genuine Vellemann Firmware "firmware_k8200_marlinv2"
based on the recent development branch

I tested the changes on my K8200 with 20x4-LCD and Arduino 1.0.5 for
Windows (SD library added to IDE manually) - everything works well

This reverts commit 935ee968a7.

Still not fine tuned but working.

* Adds config parameter `PID_PARAMS_PER_EXTRUDER` - allows single PID
parameters to be used where this would be preferable (e.g. dual
identical extruders)
* When disabled, will use `float Kp, Ki, Kd, Kc;` as before.
Preprocessor macros used to switch between.
* ultralcd.cpp defines extra menus for extra parameters only where
required
* M301 reports `e:xx` only if independent pid parameters enabled
* EEPROM structure still leaves space for 3 extruders worth, when undef
will save single parameter to all extruder positions, but only read the
first
* Switching off saves approx 330 B with no LCD enabled, 2634B with LCD
(RRD) enabled: this is significant.
* LCD modifications should be tested.

The previous calc was wrong. Between N points there are only N-1 gaps,
not N.

So changing AUTO_BED_LEVELING_GRID_POINTS to
(AUTO_BED_LEVELING_GRID_POINTS-1)

(For the SLOW_PWM_HEATERS option)

(For the SLOW_PWM_HEATERS option)

The compiler does not support comparing float values: "error: floating constant in preprocessor expression"
The loss in X/Y precision shouldn't matter for Z probes, as most microswitches or inductive sensors are larger than 1mm square anyway.

Turn off by default.

To test/enable, uncomment the #define DELTA_CALIBRATION_MENU in Configuration.h

Tested for SAV MKI and SAV 3D LCD on lewihe.

- Fixed issue when BAL area probing is shorter than it should be for
grid probing
- Warning when BAL activated with Delta Kinematics
- Fix XY_TRAVEL_SPEED when homing Z axis

Current defaults are all 255.  If it makes sense to reduce them, they should come down together, and
be in a  PID_INTEGRAL_DRIVE_MAX <= PID_MAX <- BANG_MAX relationship.

Changed Auto Bed Level to Auto Bed Compensation

Added boards.h which contains defines for all the board numbers, plus
some shorthand macros for less typing.

Changes to support displaying the real-time filament width and the
volume factor on a 20x4 LCD.  The data is displayed on the 4th line.
First the status message is displayed for 5 seconds, and then the
filament data is displayed.  The status message can be seen by
re-selecting the info screen in the menu.
