Added generic mux selection code

(and the IR ADC should theoretically work now)
Added temp reading (and it's temporary? :P )

now the mux-setting actually works (bits are cleared before set)
Added bump reading (with debouncing!)

still needs to be buffered though.
[BUGFIX] bump array is now buffered
P. Fleury's I2C lib

(some modifications)
Basic (incomplete and hacky) MPU6050 lib
My attempt at an I2C lib :P
Added previous libs to project

not `#include`d yet.
Changed some things to get MPU working

I do believe it works! :D
Added basic gyro code

Including calibration! `dt` is very large now though
