Bug with TFSBuild.exe

[Dave_Novak]

The "Team Build" action has a minor problem. When I specify a Build directory, it uses the /b option (short for /builddirectory), which is what Microsoft documents. However, in the final release of TFSBuild, this was changed to /d (short for /directory).

As is, this results in the following error: Invalid argument: /b:\\svr\drop.

This should be an easy fix.
