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.
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.
The big LCD code update. This splits the display and menu implementation. Paving the way for future different displays. It also makes it easier to modify the menu structures while keeping everything consistant. Note that this most likely breaks the translations, which need to be updated.
