Bridge beta 14 - FR add EXIFTool support

Bridge beta 14.0.0.57

EXIFTool is a powerful F/OSS tool which allows reading and writing metadata far beyoind Adobe's XMP implementation.

I have written scripts to help integrate EXIFTool with Bridge. However, it would be nice to see Adobe adopt this tool and bundle it with Bridge. I'm not even a programmer and I was able to accomplish this pretty easily.
