Deleted outdated FastServo backups
Changed PID scalar variable names to better not conflict with likely user ones
Added option to set DMP sample rate with #define MPU6050_DMP_FIFO_RATE

Uses values from 0x00 - 0x09.
Sample frequency = 200 Hz / (1+rate)
Undid my PID scalar name change, it was silly.
Fixed a tab error
Added DMP rate selection fix to finished libraries and example code
Working segway balance code, but not finished
Moved some files to outdated programs
Disabled timing code in PID by default
Changed from using bluetooth to USB
