easier macro setup

[daTokenizer]

we want to have a simpler way to set up macros then to generate an array of constants by hand.
The desired is for the user to simply type in the macros as strings into some data structure, and for this data structure to be parsed in real time by a mapping function into list of constants.

Help Wanted

1. Writing said mapping function. this is a lot of simple but requires some rigor, all the bindings are listed in file usb_keyboard.h. Also it is needed to map some characters to a combination (e.g. "H" -> KSHIFT, KH or "~" -> KSHIFT, KTILDA)
2. Determening best location for placing this mapping function. my gut says usb_keyboard.c.
