Minor formatting cleanup, note to doc some methods
remove gmail emails from test
Update monkeypatch for multipart-post to be compatible with version 2.0

Just needed to add another option to the method definition to pass along the headers hash.

I made some notes in the file, but it seems like I should be able to pass along the proper content-type and remove this patch entirely, I just can't figure out exactly how multipart-post passes along the headers yet
