[3.3.5] Achievements: progress not given

[ccrs]

Seems like recent changes to achievement system broke achievs like
http://www.wowhead.com/achievement=557/superior

Steps to reproduce the problem:

1. create a character
2. give items

Branch(es): 3.3.5

I vote 7c7b877

@ccrs Can confirm, giving items with needed itemlevel does not grant achievements.
@Aokromes I did revert the changes from commit 7c7b877, still the same, no achievement. I guess the error is in another commit.

@Aokromes don't have that commit in source and the same screenshot green items on character added in past so it works. I think it's 9b44ed9 or something in that time, items shows green and grant to achievement are added in that time. Sorry for Eng.

9b44ed9 broke it, by inverting miscvalues passed in ACHIEVEMENT_CRITERIA_TYPE_EQUIP_EPIC_ITEM (which superior and epic achievements use)
