Enabling servo usage on boards with PWM current control

Use arduino programming protocol by default for sanguino

Fix MELZI_MAKR3D to use correct motherboard

M120/M121 also set endstops non-homing state

Add Menu Items to initiate M303

Fixes for #3189

Setting a temp is still missing

Adds the parameter U to M303. If U1 is included , it will use the
PID-values from the auto-tune.

Follow-up the PR #3082, etc

Add support for Printrboard RevF

Make DISABLE_INACTIVE_X, etc., true if missing

Send position updates to RH

Patch minor spelling error in cn, en, gl language file headings

Fix lost undef Y_MAX_PIN in pins.h

Change link to the document

Fix Fan KICKSTART

Send position updates to RH where RH can not know the end position.

For example after G28 RepetierHost assumes to be at the homing-point,
but with a servo probe we are much higher. Now the RH-software-endstops
will prevent us from going down (if activated). With this patch the
internal position of RH is updated with `current_position[]`.

Sorting ot what else belongs to what if was not so hard.
But the static `ms = ms = millis();` was a bit surpising.

Patch-up to commits for Kana #3203.
Closes #3203.

Extend .gitignore

Improve Travis CI test

- Add shell scripts to help with managing configs
- Clean up .travis.yml file by using shell scripts
- Don’t download “astyle” – not needed and delays Travis results

Enabling servo usage on boards with PWM current control
timer5 is used by some boards like the Mini Rambo for controlling motor current via PWM, see stepper.cpp.
```cpp
  #ifdef MOTOR_CURRENT_PWM_XY_PIN
    pinMode(MOTOR_CURRENT_PWM_XY_PIN, OUTPUT);
    pinMode(MOTOR_CURRENT_PWM_Z_PIN, OUTPUT);
    pinMode(MOTOR_CURRENT_PWM_E_PIN, OUTPUT);
    digipot_current(0, motor_current_setting[0]);
    digipot_current(1, motor_current_setting[1]);
    digipot_current(2, motor_current_setting[2]);
    //Set timer5 to 31khz so the PWM of the motor power is as constant as possible. (removes a buzzing noise)
    TCCR5B = (TCCR5B & ~(_BV(CS50) | _BV(CS51) | _BV(CS52))) | _BV(CS50);
  #endif
}
```
Using the same timer for controlling servos results in loss of motor control. So use timer4/3 for those boards instead.

Fix extrudernum in MSG_INVALID_EXTRUDER

This is quite comprehensive. If probes are disabled in any case when they shouldn't be, I'm sure we will hear about it soon.

Delta-compatible extensions to M48

Added missing translations.
