qinqy 0.9.1

- Argh, all graphics in default there were currupt! This probably was caused by the switch to svn... Fixed it by recovering the files from an older qingy tarball.
- Fixed a bug that sometimes made qingy GUI hang on exit.
- Made DirectFB support optional. This means that you can compile and run
qingy on systems that do not have DirectFB installed. You will not get
a graphic login, but will be presented a choice of sessions and will
have access to qingy advanced features like session locking or timeout.
