Added things that MPLAB-X auto-generates when selecting compiles

This is realy not something you should checkin, but since I am
the only one working on this project and it will save me time
lets do it anyway. It can always be reverted again!
Invert UART

I like to use inverted UART since this is whats used on my
induction hob. I could of cource do this in HW, but lets
save some components.
Added new command in firmware for induction hob support

Totally untested, but compiles. Java layer is still TBD.
