Add modified camera1394 package
Sync camera params between pairs
Set strobe argument for navigation cameras

Multiple cameras on the same harness shouldn't be strobing, so only
allow one pair to have a strobing master.
Fixed conditional tags for strobe
Need larger packet size for triggered cameras
Switched to pairwise harness
Simplify image_desync

Add restart delay to image_desync
Merge branch 'image_desync_fixes' into camera_sync
Moved port nav pair to SR2
Merge remote-tracking branch 'origin/camera_sync' into sbpl
