Tag EditCloud: Added category sorting and grouped tags.

This change implements a simple category-based alphabetical sorting system that puts all tags containing ':' in front of general tabs. It also groups them together for easier styling into columns, grids, or even opening the door for drop-down categories in the edit menu. A much needed feature for me since I have hundreds of tags and I manage them all by my own.
