Further improvements!

- The Bot panel's status indicator now includes what the bot is doing
(Healing, responding to a call, arresting, etc)
- Cleans out most of the debug reports.
- Manually emagged bots can no longer be controlled though the bot
interface. Destroying or EMPing them remain the only way to stop them.
- *Hacked* bots can still be freely controlled, however.
- Calling a bot now turns it on, to save the AI the hassle of having to
do so from the interface.
- Corrected the distance-to-target calculation.
-Cleaned up some of the code here and there.
