Uses efficient server-side label creation to track which revisions are in
any given build.

Optimization: populate properties up front, discard only at end.
Bump to StarTeam SDK 11.0
Update the unit testing documentation.

Also added test.starteam.testfile value, as it is needed but was not
previously documented.
