change home route so it is calling room methods

Remove unnecessary roomQueries.js file. Change home route to be calling the methods that are baked into the room class: https://github.com/foundersandcoders/Live-Peers/blob/4402ac300ee2fc687a25e8b5417ceb5062b501c1/src/room.js
Change getUserData so that it is calling the room methods like getRoomName (etc) - might be worth making getUserData a method in room.js once this branch is merged into master

Fixes #61
