Add install vsix with unique ids for VS 2010, 2012 and 2013 #346

Add new vsix package to install ServiceMatrix, bundling the original nupattern-based vsix package, using unique ids for each version of VS (using the same id as the published package for VS 2012).
Change the id for the ServiceMatrix toolkit and vsix package to avoid collision with the install package.
Does not update the version #.
