Lightweight renaming

Hi Andrei

Great work! I've been looking for something like this for ages. A suggestion on renaming...

I propose a lightweight rename/move mechanism whereby files are renamed or moved from WITHIN TaggedFrog. In this way there is no overhead in keeping track of renames that occur natively. I've noticed when right-clicking a file in TG there is a Rename... option, but it doesn't rename the file, just the file reference in TG.

A similar solution should work for moving files.
