Lots more costumes

My maths was wrong so there aren't 250 costumes yet - only 247 but if I stop messing around and finish work early today I might be able to finish the 3 I've been working on.

Anyway, new costumes are:

* Troy - woodsman
* Dean - train conductor
* Chang - leather jacket, soccer fan, understudy, shaving and pop & lock

Other fixes

* Wheels on Jeff's train costume
* Delete Annie halloween.png as it's just Victorian by another name
