Standardized space bears.

Removed a bunch of special space bear behavior to make them like other simple_animals. Fixes #272
Adds a small Mineral Storeroom off the R&D lab so the redemption machine isn't just in a open hallway where anyone can run up and steal your minerals/ID.

Room is simple to break into as the machine will always dump the minerals inside, even if they were commanded to dump by one of the odd departments with access to the machine who aren't science. Frustrated employees are instructed to ask R&D to fetch the minerals and/or break in. It's also a fairly weak point into Science proper.

The window connecting R&D to the mineral storeroom isn't tinted so scientists can see mineral drop offs. Pressing the shutters for the front desk will now also shutter that window so they can maintain their old privacy.
There's now a door into the mineral storeroom from the hall with its own access level (64). This access level is given to every crewmember who can remove materials from the redemption machine. Namely: All of research, chemist, virologists, the bartender, and the chief engineer.
