Dependencies Update

Updates with latest versions of request and coffee-script.

Updates engines to allow node 0.10, since request has now been updated to work with it.

Removes superfluous .x and .0 from versions since they are implied with less text.

Bumps version number by one minor, since no code has changes and only dependencies.

I don't develop with CoffeeScript, so haven't taken the time to do thorough testing, though everything appears to work correctly for me.
