Fixes to .cabal file prepping for Hackage submit
Building without http-client-tls
Version bump 0.0.5
Fixed some imports
Changed documentation slightly, prep for 0.0.6.
Updated to use the new http-client module system.

This also begins a rather major refactoring that removes a lot of
needless dependencies and complexity. The Stateful module is mostly
removed so that simpler use patterns can be built atop the more raw API.
It probably could be easily added back, however.
Removed Stateful and trimmed MuLens

Removed about 3 dependencies.
No longer need to import http-client Internal
Added back "simple" OAuth module
Stateful three-legged protocol
Updated documentation about modules
Better exports in Simple (no more mapE)
Simplified requestTokenProtocol
Exported various types from Simple
