Add new core GitHub API plug-in and unit tests.

This moves the current API unit tests from the mylyn
test plug-in and creates a new package of live tests
that can be run directly against a GitHub instance.

The new core API plug-in has no Eclipse dependencies
and only relies on GSON and Apache Commons HTTP client.
