Updated config to allow you to turn off more stuff without subclassing AppConfig.
Updated tests.base.TestConfig to call AppConfig's __init__ so that changes to config defaults don't break the tests unessisarily.
Updated AppConfig docstrings somewhat.
Updated README.txt to get rid of info that didn't belong.
