Azareal 3798838ece Update the group promotion UI.
Invert the direction of the query to make promotions a little less exacting.
Make sure admins can't set the from group as the to group in a group promotion.
Shorten a field name in the word filter manager.

Add panel_group_promotions_level_prefix phrase.
Add panel_group_promotions_posts_prefix phrase.
Add panel_group_promotions_delete_button phrase.
