Fix FileManager after recent commit

Browse Source 
Temporary files should not be watched also fix a few corner cases where
the fixedname of IFile change without the file name changing.
(Oh the fun of symlinks.)

It's more consistent now, though I haven't gone through all the
implications of IFile's who's fixedName change
