Sort by Color

[BStriker]

I found it useful to be able to separate files into colour groups like this (we already have this function in FC):
- executables: exe, bat, cmd, com, etc.
- texts: txt, nfo, ini, me, etc.
- documents: doc, xls, docx, xlsx, odt, ods, etc.
- archives: 7z, zip, rar, etc.
- images: jpg, png, gif, tiff, etc.

And then to sort the files by colour. This way every time you open a folder, you will have most useful files on the top of the panel: executables first, then texts, etc. No matters which names and extensions the files have.
