Various bugfixes by Tobias Kuehnhammer (#5270)

- A stupid bug where bots re-trigger jumppads if they fell onto it.
- A small "memset" bug concerning player animations.
- Reward sounds were never cleared and thus they are played on a map restart.
- Safer and more secure handling of disconnected clients and clients with 
  malformed or illegal info strings.
- first_gauntlet_hit.wav was not played (ops/ps) bug
- capturelimit not hit (from OAX)
