Health Swap

You take your opponents health and he takes yours in Health Swap!
Whenever you take damage, he heals. Whenever you heal, he takes damage. It's that simple!

Commands:
/hs join - joins the game (only 2 players may join at a time)
/hs leave - leaves the game
/hs start - starts the game (2 players must have joined)
/hs end - ends the game

Important:
If you happen to reload or restart the server while the game is running make sure to place the players back in the game even if only to end the game to get their health back to normal.
