Add 4 methods

[worldofd2]

1:
Player:GetAchievementPoints

2:
Player:GetCompletedQuestsCount
This should have been GetCompletedQuestsCount, not sure how to update that now.

3: You also have an option to include feats of strength or not (not included by default, blizzard like)
Player:GetCompletedAchievementsCount

4: RegisterPlayerEvent

Hi and thanks for your PR. We'll look into it asap.

Please let me know if a better format should be used, first time for a PR.
Thank you.

I tested 3 about achievement and question, it seems ok

		local pAchivePoint = player:GetAchievementPoints()
		local pAchiveCompleted = player:GetCompletedAchievementsCount()	
		local pCompletedQuest = player:GetCompletedQuestsCount()			
		player:SendBroadcastMessage("Your achievement points is "..pAchivePoint)
		player:SendBroadcastMessage("you completed "..pAchiveCompleted.." achievements")
		player:SendBroadcastMessage("you completed "..pCompletedQuest.." quests (without everyday quests)")
