versioncontrol_svn 5.x-2.0

This release fixes two more bugs of the SVN backend, hopefully the last ones in the 5.x-2.x release cycle. So let's push out the "final" release, in parallel to Version Control API 5.x-2.0. Changes since versioncontrol_svn 5.x-2.0-rc2:

• Fixed compatibility with Subversion 1.4 (issue #358695).
• Fixed the uninstallation routine: before, it tried to drop a table that was never part of a released version of the SVN backend (and never will be).

The issue queue has been sufficiently quiet since the first release candidate, so I'm feeling relatively confident in pushing out the stable version. Have fun, and see you on Drupal 6 soon!
