Added Bayer filter support for color cameras

[karlrees]

• Added switch to specify whether camera has a Bayer filter or not.
• Enable Bayer-related text fields when Bayer filter selected.
• Update minor version number.

By the way, I was originally hard-coding the driver to automatically recognize color models (those passing the IsColor()) test as having a Bayer filter. I think this would be more user-friendly for new users, as it avoids the need for the user to learn about and enable the switch. However, I decided I know too little about the product line and use cases to make such a change at this point, so a switch would be the less disruptive approach.

Very useful change, thank you! Can you also update the debian changelog as well?

Okay, not entirely sure about the format / conventions of the debian changelog, but hopefully that'll do.
