Bug fixes

Changes:
1) The various bots now use their built-in radio to announce things. Secbots/ED-209's will announce arrests on the security channel, medbots will announce critical patients on the medical channel, MULEbots will report deliveries on the supply channel and Floorbots will nag engineers when it runs out of tiles. Had to rework a bit of the automated announcements to get it to work.
2) Fixes an electropack runtime, and fixes the electric chair.
3) APC's will now draw power properly.
4) The laptop's camera list now has more networks available, and is sorted alphabetically.
5) Fixes various broken disposal pipes.
6) IPC's are now truly immune to diseases.
7) Bananium crowns now let through hair.
8) Added a sprite for wearing a loaded crossbow on your back.
9) Fixes the ambulance/pussywagon disappearing when the maintenance panel was open.
10) Fixes A.L.I.C.E. not announcing the departure of the Special Ops. shuttle.
