reduce chairflipping stun

[FentonStraub]

the stun given to players that are chairflipped into is unfair. chairflip spamming completely overshadows any bit of skill either side of the fight has, and the stun allows the player who chairflipped to almost immediately get up without any chance of consequence, and allows them to set up for another chair flip just as you're getting up.

The stun given by players chairflipped into should be slightly reduced in order to actually give the player a chance to run away before the other player is already standing on a chair ready for the next spam flipping.
