Fixes tank dispenser sprites not updating, fixes combat belts not holding police tape, other bugfixes

**Changes:**
* Fixes tank dispenser sprites not updating properly when you put a tank back in.
* Fixes combat belts (from tactical storage) not being able to hold police tape.
* Fixes xenobiologists not having a preview in character setup
If you look at line 95, it was defined twice, so I removed the second one.
