Removed part of the code, forcing you to use /svn/ as repository root

I Removed part of the code that adds /svn/ to the subversion.path from the config, which forced you to use a folder /svn/ as your repository root.

I worked with it for a few days now and it all seems to work. I don't know if you need this change, but I found it a lot better to use than a hardcoded /svn/ as repository root. Now I can use something like /home/svn/repos/
as root.
I have not touched the testfiles, but it seems it is hardcoded there too.
