Make testcentric.extensibiltiy.dll available as an independent package.

[CharliePoole]

This will make it more easily usable outside of the engine. It will become a dependency of the engine.core assembly as well.

[CharliePoole]

The package is now available as a dev build on myget: version 2.0.0-dev00004.

Work remaining on this issue is to remove TestCentric.Extensibility from the engine build and make it a dependency.
