GPS module now updates GPSPosition UAVObject
rather than the PositionActual object. The
GPSPosition object is intended to be consumed
only by the AHRS. The AHRS will use this (and
other inputs) to compute a filtered version of
the position in the PositionActual object.
This commit will cause temporary breakage of the
GPS functionality in the GCS until the PositionActual
object is properly updated by the AHRS. Most of the
GCS should continue to use PositionActual. The only
exception to this might be any tool for specifically
visualizing the raw GPS state.
GPS.c is now only responsible for receiving a
complete NMEA sentence from the COM interface.
NMEA parsing is now factored out into NMEA.[ch]
which is where GPSPosition is now updated based
on the complete NMEA sentences obtained from the
GPS.
Latitude and Longitude are now encoded in a
fixed-point notation in units of degrees x 10^-7
to prevent truncation of precision due to encoding
into a float.

1. Added reenumeration function and call it on USB init (device will appear after reprogramming now)
2. Moved buffer.c to general flight/Libraries location
3. Removed the 62 byte transmission limitation by adding a transmission buffer
4. Sped up USB communication by increasing endpoint polling frequency
Note, that the nonblocking and blocking USB send functions are not blocking entirely correcting. The blocking calls the nonblocking, and the nonblocking blocks until the last chunk has started tranmission if it's a big transmission. The buffering I added would generalize to non-blocking nicely, but would require using the EP1(IN) callback to handle most of the tranmission. This creates a lot of issues if one function is pushing data onto the buffer and the interrupt is sending.
