Update README.md
Much has changed, but PythonTester.py is healthy.

Removing all sys.path modifications, except a few instances where I modify it temporarily,
 then restore it.

Removing Dependencies on imports from top-level sys.path

Removing Dependencies on modules loaded into namespace as side-effects of other module imports.

Edited PythonTester.py to conform to the stricter namespace considerations now.

Added a few notes on 'moving forward'

Hoping there are no pdb's hanging around that I missed.
Merge branch '3.1.6-flip' of https://github.com/flipmcf/Kaltura_API_Python into 3.1.6-flip
Use abc.abstractmethod for interface model
Base the PluginBase class off of IKalturaClientPlugin

It's really just equating the class descriptors now.
