Allow the user to specify the viewfinder resolution instead of guessing

Browse Source 
Guessing badly prevents the camerabin pipeline from loading at all and
the fallbacks used are not representive of the capabilities of most
cameras. So either stay out of the process and let gstreamer negotiate
a resolution if it can, or use a resolution supplied through the viewfinder
settings control by someone hopefully better informed.
