Update III - Co-op improvements

The co-op update is now in the default branch! It includes a lot of co-op improvements including reviving, co-op perks and balancing. The difficulty may need some adjusting but that depends on the feedback - so let us know!

I'm posting this third major update on Sunday as it seems some players are experiencing a couple of bugs in the Dark Caverns which have been fixed already in this build. This way less people will encounter them.

Here's the change list:

Added local co-op setup screen for controller management

Co-op run ends when all players are dead, instead of any player

Level exit network coloring by co-op player
Fixed co-op health persistency issues
