MNAV 1.5

From forum, I found that Kpsi is not updated (although the heading is corrected), so is P associated with heading. This version fixes this problem. In addition to that, since Stargate is not available any more, this version is compatible with Gumstix compiler (at least it works in my gumstix setup).

Servo Mapping

The MNAVs with old firmwares have un-intuitive
servo mappings. The latest firmware (version 1.3)

For those who have the firmware version of
