OpenSocial Containers Based On Environments

The idea here is that each environment in the Playground can represent it is own container.  This will allow developers to configure gadget OAuth data based on an individual environment.

To do this we need to construct a unique id from the environment that denotes the container.  This is necessary since there is only a single shindig server for all apps running on Domino.  Consider if we were to copy the NSF for the playground on the same server multiple times.  We don't want the containers/environments for each NSF to step on each other.  To this the container id for each environment follows this patter

[NSF file path]:[NSF Replica ID]:[Environment Name]
