Need for %FILE_TYPE% template variable

Hello Lester,
the plugin works great. It would be even better with a %FILE_TYPE% variable which would give me only the file extension part (without the ‘.gif’ suffix). I would like to use the great font awesome icon set instead of the image icons.
Any chance you will implement this?

Thanks in advance,
Oskar
