Huge rush before presenting the product : switched all the UI to fit a 20x4 chars LCD, Added a disclaimer, Added the BOLUS feature requested by doctors

Worked on feedbacks from lo2, now using MEMORY_XXX_MSB and MEMORY_XXX_LSB for better readability, a bit more documentation on variable usage

Added the pre-alarm feature that will allow users to set a configurable warning before the end of the injection. Added lots of comments for code documentation.
