There’s no need to ask users to uncomment Max Endstop pins when they
have them. These will be set to -1 later if the endstop option is
disabled.

#1405 includes some changes to pins.h for a 4th extruder. This commit
applies those changes. It also deals with a possible problem with
SENSITIVE_PINS.

All the additions look proper. I can't think of any other extruder-count-related items that you might have missed. So, with some optimism, I will merge this for testing.

Hopefully this is helpful to organization and future expansion….

Add PID_dT in temeprature.cpp

Proposed fix to #1379. Printrboard I2C LCD support

Pins 2 and 3 are probably general-use pins, since the filament sensor
uses pin 2.

Code wont compile with extruder but without bed runaway protection defined.

Without this fix, the code wont compile with extruder but without bed
runaway protection defined.

removed function step_wait() from stepper.cpp

Add: Board for Vellemann K8200 (derived from 3Drag)

Fixing a build error for melzi and gfx display

Add proper delay in stepper.cpp

removed function step_wait() from stepper.cpp because its used nowhere.

Issue #1385 describes a delay that the compiler is optimizing out and
this solution.

# 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

## Add: Board for Vellemann K8200 (derived from 3Drag)

* Boards.h: updated comment for board 3Drag - K8200 removed
* Boards.h: added `BOARD_K8200` with ID 78

* language.h.: machine name and firmware URL for new board

* pins.h: added `K8200` to any `#if` with `3Drag` and corresponding
comments

Update Boards.h for Vellemann K8200 - comment only

Remove hardcoded programmer option (-cwiring).

This reverts commit 935ee968a7.

Still not fine tuned but working.

When a melzi board and a full gfx are both selected, the build fails
blaming for some missing defines.

This is a fix for the issue: now my configuration works.

## Update Boards.h for Vellemann K8200 - comment only

* Boards.h: updated comment for board 3Drag - K8200 uses same board

This reverts commit 5333590ac2.
