Fixed a light issue in Security Maintenance (thanks to muskets).

Update to Bridge.
More updates to CentCom. Added doors (elevator sprite) to CentCom but they are inaccessible at the moment.
Added new weapon sounds: blaster, laser, pulse, wave, emitter, and one for the marauder canon. Not all are used at the moment.
New sounds for the energy sword on and off states (they're unlicensed, I promise).
Added/changed alien attack sounds.
Added some more messages for aliens attacking mechs.
