camerabin2: Changing how some properties work

Browse source 
Some properties (like viewfinder-filter) only are taken into use
on NULL->READY transitions and the get/set property was returning
the currently in use value, instead of the last set.

This is bad, as after setting 'a' to 'x', you expect that getting 'a'
will return 'x'. This patch fixes it.

If needed, later we could add current-* properties that are readonly
and get the current value in use.
