Dropdown with possiblity to select bacground image.

Basically this
It should work with GET params or slash param
room.gametactic.com/{game}/{id}
room.gametactic.com?game=xxx&iyyyy
Then we have
maps.gametactic.com/{game}/index.json
which contains like

[
  {
    "name": "Map Name",
    "path": "new/somemap.png"
  }
]

So this maps stuff will be on another repo and can be updated without updates to codebase. We could even use github as cdn for the maps as it's static data.
