Room reservations 0.2d release

I've released room reservations 0.2d, for OpenACS 5.1.

Room reservations allows your company to keep track of room reservations online.

Changes include increased performance (removed extraneous permissions creations) and fixes to the UI (many internationalized entries were incorrect).

For developers: I've set up room-reservation on the oacs-5-1 branch, so further development can happen there.
