[Johnny got his gun]

0.2 up

0.2 050201 Added progress bar. Time of the oiling process is default at five seconds. Tweakable through the new cvar "oiltime". In previous version, when you pressed the use button in front of a door you actually emitted this small "beep" sound, likely noticable by players with good hearing. This is removed, so the oiling process should now be completely silent.
