Action + Selection Feature patch

This patch adds the Action and Selection feature implementations for Shindig as specified here:

http://docs.opensocial.org/display/OSD/Declarative+Actions+Contributions+and+Selection 

There are some small changes to the spec and I have attached a patch for those.  Unfortunately all patches need to share the same base for this tool so the diff view won't work here.

I have updated the main feature patch after running gjslint.  You can ignore
patch set 1.  See patch set 4 instead.  I would delete patch set 1 but thought
someone might be in the middle of adding comments.
