Move flipping the image to the CameraInterface class
Suppress output of system commands for flipping image
Make the output of the jpegtran command the same as the input file

Meaning that I no longer have to delete the original image and rename
foo.jpg afterwards. Yet to be tested.
Remove application directory parameter from camConnect

This is now passed to the constructor since it's used in two places.
Add options flip and disable picture taking

These have yet to be tested.
Fix checkbox layout
Add methods to retrieve the camera and projectors' posemats
Set pose matrices in the camProj module upon scene creation/loading
Add a weight to each mapped projector pixel

Currently the weights are always set to 1.
Calculate pixel weights
Use original photometric normals instead of scenepoint normals

The results are a lot better than when I tried to use pure triangle
normals.
Add button to generate weight images

The weight images just fill each pixel with its mapped weight as
determined during calibration.
