Vcs: Simplify state detection code

Browse Source 
Simplify handling of temporary files, clean up and simplify the code a bit,
remove "project nodes" which can not be open in an editor (and do not use
the '#'-syntax anymore).

Side effect is that files in git repositories in $TEMPDIR now work as
expected.
