Big commit coming

A big commit to SVN is coming quite soon.
I cannot tell yet when exactly, but I've done a lot of work on the code and soon it will again be in a state that works (right now a few things are broken because some things got recoded big time).

Most files have experienced at least little changes and the update will introduce the planned features of flexible version-trees.

Also some other stuff has been done, but the biggest update is the version-management, which also is the reason why my local codebase currently is broken.
