Added stopwatch tasks through most of the code hit during a platform build.

Added sf-scrub-build, for completely freeing up the resources used by a build (ie deleting it from the HD). Removed import of generated ant script as it had no effect, and was causing strange failures with sf-scrub-build.

Code to automatically find a physical drive for running a build, triggered as necessary.

Added new logic to deal with drive letter allocation when builds are launched from Hudson.
