patches for downstream from Benjamin Drung
update from Benjamin Drung
start_menu.blend: using the file trom revision 72 I reapplied the patch from Kemeros, because the characters were missing:
* joystick button to skip intro
* joystick limits 1/10th on up/down to stop analog joysticks moving the menu all the time
Fixed level scripts.
chnages so this can use --nojpeg argument to compress PNG's in place
