FreeEMS 0.0.7

Changes:

Moved pins for ignition around
Changed obsolete code in main.c with idea inspired by Alex
Tidied and removed some TODOs
Added port A and B access together for ignition output (registers are conveniently next to each other for word access)
Moved PWM experimentation to a function and init.c
Shifted all macros for main injectors to freeems.h for use in (at least) two source files
Rearranged and changed all global variables
Added new status and settings bitwise variables
Implemented very basic NipponDenso decoder that I would not trust to do much at all.
