Incremented setup.py version to 0.1.4
Added __version__ variable
Fixed some more charset bugs
Reworked controllers to be instantiated once. Controller methods now
receive request and response objects as parameters.
Decoupled Request and Response objects. Moved response rendering to
WSGIAdapter.
Changed Response to inherit from Exception and thus be raisable in a
controller method to return an arbitrary response.
Added an iter() call in OutputBody to help ensure that only valid
objects are returned to the gevent wsgi server.
Fixed tests to work with recent request/response decoupling.
Simplified some test setup.
Added release file.
