Add feature to briefly run the cooling fan at full speed when it first starts.

Finnish language

+ Finnish translation

Add a feature to run the cooling fan at full speed for a small period
(default 100ms) when first starting the fan.  Some fans wont reliably
start spinning at low power, and many fans have issue with the PWM at
low power.  However, once the fan starts spinning it can reliably be
set to a wide range of PWM values.

Always set the FAN PWM value in check_axes_activity() and always use
the value of the active move if a move is active.

Makefile sanguino

Fixes issues # 216 and # 135 for Gen6 and Gen6 Deluxe board

Power signal control definitions for other power supplies

Added optional feature to stop printing when an endstop is hit. Made the Z display on the LCD in 3.2 format instead of 3.1. Added LCD message when and endstop is hit.

Definitions for Sanguino SPI

Small changes on the LCD panel, let the speed control work better, line up the parameter edit the same as the menu, remove some unused defines, and remove the Z from the 10mm move menu.

Automatically set *_MIN_PIN and *_MAX_PIN according to *_HOME_DIR.
