Add flag for using white for missing materials instead of error

[GoogleCodeExporter]

Add a flag (for example -w) that would signal that a solid white material will 
be used for all missing materials instead of causing and error and the 
compression to fail.

Once again I have a solution for this created already, but it seems as though 
you are not working on this project right now.

Hi Jeff, sorry that this isn't my top priority. A default material sounds like 
a good idea.

I understand that this isn't a top priority. I went along and made it for my 
own uses since our pipeline requires it...
