Difficulty level 1-3 supported
Require SDL_image
Show difficulty setting on gameover screen

Nifty buttons.  About damn time, right?
Thanks to sibn for the above!
Bugzilla bug #46 (https://bugzilla.icculus.org/show_bug.cgi?id=46) should be fixed, thanks to jwr!
Changed to SDL_image for the logoscreen loading, changed to a PNG.
Further: No more bmps will be included with releases, all images will be
PNG's. Note that bmps will still be in CVS, so as to preserve the source art.
auto* stuff, thanks phaethon!
Music! Thanks to Pajama Crisis (Emmett Plant) and xiph!
Note that we now also require SDL_mixer!
Ungrabbed and paused modes display mouse cursor, to indicate crosshairs are uncontrollable.
Pause and boss mode releases the sound device and reopens on resume -- if sound device is in use by another program when resumed, you may have problems.
When paused, resume by pressing 'p', ESC, or double-clicking the mouse.
Removed getopt requirement, built in petopt instead.  Blame sibn for this one.
We added a Makefile for OS X (Makefile.osx), thanks to Ryan.  He also helped fix the flickering problem on OS X, w00t!
I changed the logoscreen too, need a real artist to clean it up.
Finally got rid of the bizzare newlines from windows.

Thanks to jwr for the above! 
Double buffering, can't remember who asked for this, but it's in.
