adb5375a09 Enabling servo usage on boards with PWM current control
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.

8b876241bd Some more servo code tweaks
Just set up the pin. Don't move to a random position.

Simplify servo::move()
* servo::move() does not need the pin parameter - The pin is set during servo_init() with attach().
* servo::move() does not need a return value.

SERVO_LEVELING is the wrong condition to deactivate the servos.

Remove some temporary (Servo *) variables.
SanityCheck for the servo indexes.

3b23ccd366 Patch servos code for move
- Have `Servo::attach` explicitly return -1 if it fails
- Check for -1 in `Servo::move` because `servoIndex` might be 0
- Make `attach` / `detach` calls conditional on `SERVO_LEVELING`
- Move `SERVO_LEVELING` define to `Conditionals.h`

2ddb2a2be9 Add Servo::move() to servo.cpp
move(pin, angel) - Sequence of attach(pin), write(angel),
                   if DEACTIVATE_SERVOS_AFTER_MOVE is defined waits SERVO_DEACTIVATION_DELAY, than detaches.

As we have jitter on the servos during moves of the steppers, and detaching them improves this behaviour,
the usual sequence to handle a servo movement is:
attach(pin)
write(angel)
delay(until the servo finished the move)
detache()

Here a function to handle the complete sequence.

59529b755d Fixed lowercase change missing on commit a22a228b.
Servo.cpp and Servo.h were changed to lowercase in Makefile but not their actual filenames.
