removing tfs files... and a class we don't need

removing data population class for sql server provider to unity b/c
we're only using db backups right now for that setup... also removing
tf1 and tfb files b/c they're a pain and don't belong in git--they're
only there b/c I'm running tests with TFS Build and am using source
control there for my tests---don't worry, github is still my master repo
for this stuff.
