svn: added support for hooks management of git and subversion.

- new svn hooks that allow execution of rhodecode integrations
- unified hook handling for git/svn
- this code is backported from rhodecode, vcsserver which executes hooks
  is proper place for this
- hooks are now installable via remote call of rhodecode to specific repository
