Migrate Matches to new model

[chbfiv]

improve match design. Suggested: 1) one match list with iterators for your turn, their turn, and completed 2) separate your turn, their turn, and completed match list

get moves to be done on the "match" object

• MatchCurrent refactored to OpenMatch which extents Match
• MatchCurrentList refactored to OpenMatchMap
• OpenMatchMap extents HashMap<String, OpenMatch>
• MatchCompletedList refactored to ClosedMatchMap
• ClosedMatchMap extents HashMap<String, Match>
• MatchMove instance list needs to be moved into Match from the MatchCurrentList
• OpenMatch contains Actions/data structures that can only be conducted on an open Match
• Match has everything else
• OpenMatchMap instance is used to create new/random matches and provide filters on the open matches
• Match and MatchOpponent are identical classes.
• All doubles should become floats.
• All String fields that represent other core Types should be stored as their core type and boxed/unboxed to/from the request; e.g., UTC time stored as strings should be Date

Related to the match design let's say we fetch and store the moves with that match object. The get moves call can get all or the last n moves. There was a request by a developer to be able to quickly determine who made which move, so was thinking we could have a list of move objects with one field being the user who made the move, but if the move data wasn't fetched that would just be null or with a flag that says fetched.
