Updated restler library to latest (3.2.2)

I ran into some EventEmitter issues that stem from the Restler library:

This has been [fixed in the latest version of restler](https://github.com/danwrong/restler/issues/129), so I have updated and run the tests on my fork and everything passes. :)

Thanks for the library
