start pvp

I think Im going this route:
1. Load lobby list
2. Load Player stats
3. Player selects an available lobby
4. Player joins + websocket connection starts
5. Update player positions/states via websocket on position change
6. End websocket connection when player leaves

Tomorrow I'll work on the server side and create a view for #3 in the app
