More defibrillator work

- Fix string for activating and de-activating the defib
- Changed values to be closer to my previous changes
- Changed a few strings
- Re-added set-up delay
- Defib should no longer revive bodies when they have no client. That's
what happen when you redo changes only halfway
- Re-added temporary eye blur and paralyze on defib. By all measures, it
should not cause further problems
- Added very slight damage on each defib attempt, regardless of success.
25 % chance of heart damage if SUCCESFUL and rand(1, 5) burn damage to
chest every time
in simple_animal mobs yeah they can go from stat DEAD to CONCIOUS if you increase their health to above 0. But all other mobs stop processing past a certain point when they die and their stat var doesn't update except by outside sources.
