Latest progress

Just a little note on the latest updates for Snow Problem:

- extra platform type added - "Melter" - this does what you would expect, let your snow touch this and it will instantly evaporate. This will allow for extra flexibility in designing the levels.

- whether or not it will be noticeable I don't know, but some code added to improve overall performance 

- more levels designed and tested

- music and sound effects added

It's coming along very nicely! :-) When I get time to work on it, that is... :-/
