qingy 0.9.2

- Since shutting DirectFB mode down sometimes fails, due to the fact that
DirectFB itself may hang somewhere in its bowels when closing graphic mode,
I wrote some code that performs a low-level reset of the console,
thus effectively restoring it into an usable state. Now, when qingy has to
shut down its GUI (and it hangs), it will kill it, reset the console, and go on
as if nothing had happened :-)
- Fixed shift-tabbing from username to session.
- Removed 'retries' entry from settings file.
- Removed --screensaver command line arg, moved it to settings file.
- Added support for screen power management, now the screen(s) will be
powered off after a given timeout.
- Fixed a bug that made screen saver pop up immediately when user chose
to disable it by setting a timeout of 0.
- Small logger improvements; log more events in debug mode.
- Fixed bug that made qingy respawn indefinitely if one chooses syslog
as the only logging facility.
- Fixed bug that made qingy GUI crash if console was not chosen
as a logging capability.
- Fixed corrupt matrix screensaver font file.
- Made last session files in user home dirs owned by the
respective users, and no longer by root...
- Added some code to get available X sessions for those
distros that do not save them.
- Other fixes and clean-ups.
- DirectFB version 0.9.24 (or higher) is now required to run qingy.
