Overchannel and missed bashes

[Aureus]

As of the next reboot:

• Overchannel gives noquit. This was needed to avoid scenarios where we were starting to see people use it, quit to drop the aff, and log back in to use it again with less risk of exploding
• The risk/reward on running bashes against a stabber was way off, so...
  • ...sitting no longer gives either a regen bonus or a stab damage bonus (resting still does, as sitting and resting are separate)
  • ...missed bashes lead to a disengaged sitting state less often than today
