Revision 270490

- Add "label" attribute on checkout per request from Greg Frank - checks out a specific view label.
- Add "recursive" attribute as in the deprecated <starteam> task.
- Add "forced" attribute as in the deprecated <starteam> task and avoid checking StarTeam statuses when true.
- Make sure all exceptions are caught on execution and rethrown as build exceptions.
- Fixed a bug (using the "forced" attribute) which were causing files to be incorrectly not checked out when a rootLocalFolder was specified because the StarTeam file statuses were being checked in relation to the default directory.
- Fixed a bug where files were deleted immediately after being checked out when a rootLocalFolder was specified because the task erroneously thought the file was not under starteam control.
- Code layout to fix weird indent issues.
