CMIS Binding for MediaItems & Albums Services (issue2193045)

[Wo...@gmail.com]

Reviewers: dev_shindig.apache.org, Han Nguyen,

Description:
I've created a binding for the Albums & MediaItems services within
Shindig that interacts with a live CMIS repository instead of the sample
JSON DB.  CMIS Folders & Documents are mapped to OS Albums & MediaItems,
respectively, and vice versa.

An ActivityStream notification piece is also included, which spits out
an ActivityEntry for each CRUD operation performed with Albums &
MediaItems.

Includes all project configurations necessary for the bindings (e.g.
modified web.xml, service binding, etc).  Note that this project depends
on opencmis-client-api.
