Version Handling

[msaint]

Hey Naveed,

I merged the last 2 PRs immediately because your update actually broke the client due to the fact that the version number was being already automatically added to the request url by the raw methods.

If you could take a look at the updates I made and see what you think, would still love to get your +1 on it (even if its after-the-fact) :)

I'll plan to add some functional tests that make a few API calls.
