Split client out of main __init__.py file

[rlotun]

The current structure of the library mixes OAuth signing tools with http client library code - specifically synchronous http library code. We use Twisted, and would like to use all the great signing code without having to have httplib2 installed.

I'm thinking it might be nicer to have it moved to the clients sub-package and possibly have some import logic in init.py with a try/except ImportError around httplib2.

Yeah I ran into this issue as well. Ended up forking the library
and moving the client and server into their own modules. This way I avoid that hard dependency on httplib2.

Got nothing against httplib2, I just don't use the OAuth Client or httplib2 directly.

Fork no longer exists but a valid request none-the-less. Thoughts @joestump?

I agree we should split up the monolith that is __init__.py. Was just thinking about that this morning.

Easy enough for 1.9RC1 or schedule for 2.0?

[joestump]

I think we should get 1.9RC1 out with as many bug fixes so my vote is to save this work for 2.0.
