Added context menu and uncolorize action

Adding objects now actually updates the bounding box like it should be.

Camera is now stored to configuration so it is preserved across program shutdown. I don't know how significant this is but eh

Switched the object list from a QTreeWidget to a QListWidget-derivative. Derivative because I'm going to add a context menu.

Added new BFC dialog

Corrected camera icon order (and association), added tool tips
