Update calibration launch files
Run navigation cameras at 752x480

Don't synchronize as wel, but the extra width is very nice
Be more careful about shutting things down in desync

more precise targeting of just the one nodelet manager
Make Cameracalcs run standalone

no plots yet though
Another interesting point for a set of test cameras
Merge branch 'namespace_changes'
Merge branch 'master' into cameratuning
Tighten desync tolerance

These cameras do not sync in fomrat7, keep trying
until they get close.
Checkerboard used for 752 calibration
Merge branch 'cameratuning' into hydro
