IcedCoffeeScript (.iced) content type support

[am11]

@madskristensen, now that we are supporting .coffee and using IcedCoffeeScript compiler (#353) and added basic test as well, please add support for .iced content type.

Also, are you guys planning on OOTB support of .iced file type in vNext of VS?

I have shared PNG and ICO for IcedCoffeeScript on SkyDrive. 8-)

I believe that actually adding support for Icde CoffeeScript's new syntax wouldn't be much harder; create a new ContentType that inherits CoffeeScript, and write a classifier that highlights await & defer as keywords. It looks like there is no new syntax.

@madskristensen, thanks! Can we also bring .iced file extension support with the IcedCoffeeScript icon to VS via WE?
