Just a quick bugfix patch. Details below:

Changelog for 1.0.4:    

General Fixes:

-Playing the tunnel scene from the gallery part of the way through, exiting via the locker and then immediately playing it again would result in a number of things being in the wrong state because switches and variables were not reset. Switches and variables are now reset on exiting via the locker, and the scene should play through normally on restarting it.

-The "2" on the glory hole oxygen gauge is now at the bottom corner of the O, not the top.
