Release 0.12.0

With [Communicon](http://communiconcentral.com/) coming up this weekend,we thought we'd better give you a new release to go with it!

**Changes**

* **Collisions** - we've changed how we draw and calculate blocks and collisions - this is a HUGE change that should stop people on slower computers falling through floors/corners and affects every single level in the game so please test thoroughly to check we haven't missed anything
* **Strip poker** - run out of clothes while playing cards? Not a problem if you're playing as Jeff, Pierce, Troy or Chang - bet your clothes instead.
* **Updated in-game costume select** - you'll now see a large image of the costume you've selected
* **NPC text outlined** - making it easier to read
* **Sandpits** - made the hidden entrance easier to find
* **New Weapon** - ghost peppers - buy them from Juan in Taco Town
* **Updated intro** - more green code to match the episode
* **More savepoints** in the sandpit levels. We know how much you hate those moving platforms!
* **New Costume** - only one this time - "Naked Troy"
* Bug fixes
