     Updates `totalVotes` amount of proposal with index corresponding to `proposalId`.
 
-    If voting first bit of `vote.roomIdAndType` is 1 that means that vote is for and `vote.tokenAmount` is added to `votingRooms[roomId].totalVotesFor`, otherwise if `vote.roomIdAndType` is 0 `vote.tokenAmount` is added to `votingRooms[roomId].totalVotesAgainst`.

     After that add new address to room `voters` and updates mapping `voted` accordingly.
