New Tags Added!

Quick technical announcement:
I added a few more tags today to all appropriate posts. You can now browse content tagged by:

• Game engine (such as Unity or Game Maker Studio)
• Available platforms (Mac games, Linux games, PSP games)
• Game perspective (2D, 3D, isometric)
• Controller compatibility and a few more. 

I didn't add a 'Windows games' tag as all games on here (at least so far and in the foreseeable future) are Windows-compatible.

I'm also trying to find a way to improve the tag/label page - I realize it's pretty messy-looking.
