basic gamify api routes

[trriplejay]

• create a simple steam/mock_webapi.go that will implement basic methods for get players, get games, get friends, and return static (mocked) data. for now, data should be loaded from json files stored locally, not in the repo.
• implement an api for gamify that utilizes these mocked routes, and filters the data down to only the data we care about.
• determine a format for the returned objects. be consistent and allow for enhancement over time

have some basics done. our api will need to enhance the steam api a bit.

example:

• steam API for a get friends call returns an array of objects that just has "steamid" and "friend_since". This won't be useful to our UI.

internally, when our API /friends?steamId=xyz is called, we need to do the friends call for xyz, and then do a steam get players call, passing in the list of steamIds from the friends call, then what we return should be a list of players. working on this now.
