- Fixed: The alpha property of status bars didn't work anymore.

- Added: alpha command to SBarInfo which allows you to increase the translucency for certain parts of the status bar.
- Added: reverse flag for drawkeybar which reverses the order in which rows are filled with keys.
- Changed a gamemode statement to an else in the Doom hud since the frag count and keys should never be shown at the same time.
