Properly support VSTS 2010


Currently the software is built against the TFS 2008 APIs, and the setup project includes a dependency on Team Explorer 2008. This task could be approached in one of two ways. 1) Investigate whether a single application/setup project can be built that can target either the 2008 or 2010 APIs. 2) If a single application/setup project is not possible - then prepare a separate build that supports 2010, and provide separate installers for each.
