Changing the way the container works, avoiding a monolithic
container, and supporting Organization/Application hierarchy
for registration of Resources.

De-emphasized the need for RootResource, while simultaneously
requiring all resources (including root-like) to track parentage.

Add Extension mechanism to provide more flexibility in deploying
Resources for any given Application, instead of the bare ctor-based
previously used.

Re-wire standard /subscriptions resource for all applications.

Add some basic helper scripts. (create_organization, create_application)

Bring in netty for SPI (needs to be filtered better) for ByteBuf operations.

Comment-out test-suite.
Re-enable integration testsuite.
Better activate for OSX.
