Updated to crio-FPGA-control-v3.

-FPGA Main has been updated to allow V*, Force, and position data to be sent up to the PC level when in "Manual" mode.
-UI Main has been updated to include:
 *A control for changing the control loop frequency (Control period) in the 'Control Settings' tab
 *A display for showing the actual control loop frequency in the 'Data Monitoring' tab
 *Butterworth filters on all the data to filter out frequencies below (display frequency)/2.
 *A 'Retain data' toggle to switch between retaining all the data (ON) and retaining only the data shown in the
 graphs (OFF). This is to prevent massive amounts of data from being accumulated during data monitoring if desired.
