Merge pull request #161 from vergenzt/develop

Add Grunt watch task
Include all .ts files from referenced projects when building

Only problem now is how to deduplicate resources. i.e. when you have a
bower_components per project, how do you not duplicate the dependent project's
dependencies that you're also dependent on?
Add exported source folder setting to build path

This solves the problem of duplicate dependencies. :) Now you can just set only
your source folder to be exported.
