1st draft of pretty large scale refactoring to facilitate more flexibility
 * contexts.ini to relace functionality of factories.ini the way it probably should have been from the get go. Configure the collaborating objects for a given context.
 * deprecated Controller::getInstance, it's not a singleton but is an abstract factory, use newInstance instead references #37
 * somehow fixed the tests, maybe by removing the kludgy mockContext stuff..
Was getting reference errors when using keys with multiple dots, refactored a little and added test for ReturnArrayConfigHanlder
Various changes.. seems type checking against inherited classes is going to prevent pulling a mock through that process.. 
it would work if we type checked for an interface, but I guess I'll look for another way around it instead.
Added Daniel Swarbrick's contribution to fleshing out the PDO driver.
Added optional parsing of values into true boolean values
more clean ups..
If smarty cache directory's defined, then use it
