Implemente getXp, this method calls a StoredProcedure (GetDifferenceExperienceByMatch) to obtain a result set with the time vs. xp diff for a given match passed as the method param.
Changed the datasource for the XP Graph from timeline_xp to match.xp
New implementation for generating the xp graph. Now it uses the data from a StoredProc in the DB, no calculations required.
