support for 'events' core module

[ghempton]

fixes michaelficarra/CoffeeScriptRedux#183

[michaelficarra]

Why was node's events library not working for you?

[ghempton]

The test included here fails (a simple require 'events'). Gives the same issue as I was having in CSR.

Ah, I see now. As of 0.10, events now depends upon child_process, which hasn't been ported or made available for obvious reasons. When I add the test and run the tests, I get this output, which is much clearer:

Sorry for the lack of clarity. The error in CSR is actually different than this one I realize. For some reason require 'events' simply returns null in that case. Well regardless, this fix does fix the CSR issue.

@michaelficarra done

Thanks, @ghempton.
