So, back with the changes. It toook a bit longer because I accidently run
an "svn revert" in the wrong dir but luckly had the changse from an
"svn diff" run in the terminal scroll back. Just that I had to sort the cut'n
paste recovery :-)

Here are the only parts that are not yet commited, do not apply to trunk
anymore and need a cleaner implementation. The bottom part just
wiping some files and copies some tiny versions over can be trivially
be pushed into trunk by defining a new post image hook. The filtering
is a bit more tricky to get pretty:
