   - "cancel-match": User cancels a current matching request
- Added server-sent events:
   - "connect": Server successfully connected with user
   - "disconnect": Server disconnected with user
   - "finding-match": Server trying to find a match with other users
   - "found-match": Server found a match for this user, returns match object
   - "no-match": Server could not find a match within the timeout
   - "disconnect-while-match": User was disconnected with server while finding a match
