In all these cases we want the axis to be homed. If we could have lost
some steps is secondary.
Reenables homing seperate axis with DISABLE_X / DISABLE_Y true.
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[]`.

Fix for commit b0f5ba0: Z offset: -front [of the nozzle] +behind -> Y offset: -front [of the nozzle] +behind
Standardize the writing method: Z-probe, z-probe -> Z Probe

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.
