Skip specified file types

[mobileka]

Skadi tries to render NEF (loseless RAW images by Nikon) files. The problem is that these files are huge and it takes a lot of time to load them. Moreover, the end result is bad because Skadi is not able to render these files properly and outputs a very small thumbnail-like image as a result.

It would be nice to have an option to skip certain file types or maybe completely skip NEF and some other RAW image formats.
