Added checks for the player being dead, stunned, unconcious ect... to:

- Timers
- Remote Signallers (Fixes issue 325)
- Proximity Sensors
- Infared Sensors (Man.. these really need to be fixed.. or just re-done entierly)

Cargo shuttle:
- People in the area of the cargo shuttle get gibbed when the shuttle shows up. (Fixes issue 508)
- Renamed 'Dock' to 'Away' because Station -> Dock is confusing...

Committing for Sieve:
- The toggle throw hotkey (end) now works with TK (Fixes issue 523)
- Borg diamond drills now properly dig sand (I still don't understand why they don't just have a shovel...)

Updated changelog to reflect some of these changes.
