* Added support for custom window sizes (by editing prefs file)
* Fixed assertion failures when changing levels in net games
* Restore the previously selected map when finishing a net game
* Restore support for UTF-8 prefs / MML (while preserving compatibility
with broken Rubicon MML)
* Added a VSync checkbox in OpenGL
Also, fix dependency on vorbis, so ogg music plays correctly.
