Core/LFG: implement weekly reward counter to limit the first dungeon rewards

* all default random rewards can be rewarded 7 times per week
* raid finder first reward can be rewarded once per week
* if completionsPerWeek = 0 the currency caps will limit the first rewards otherwise first rewards can be always rewarded
* random Cataclysm normal dungeons will now reward 140 Justice points instead of 150
* second reward for random Cataclysm normal dungeons will now reward gold only (need to verify this)
