Added AggregatedStats class
Switched API calls to versions 1.2 and 2.2
GameType now has AggregatedStats as a field instead of just dumping the array into the stats field
Switched teamId to fullId in Team
Added getRevisionDate() method to Summoner
getStats() in Summoner now returns the stats field with the GameTypes instead of a direct response from the API (will also preload if not already done)
