ROOTKIT v0.2.1

• The settings screen is opaque: the pause menu and the shop no longer show through it (#1, thanks @STRML).
• Abandon run from the pause menu works again.
• A host closing the room ends the client's run cleanly instead of crashing it.
• Co-op through the relay starts reliably.
• The relay only disconnects a peer it still holds.
• Lobby start delay scales with the roster size.
• Per-session net diagnostics behind --netlog.
