Bug 3643: Add another regular expression to match new perl version output.

Fix handling of directories of builds

Add delete_builds.pl - a utility for making space quickly on build machines This Perl script deletes some directories known to contain very large files first, before deleting the rest of the build which contains millions of small files. Given multiple builds, it will do this breadth first, so that lost of space is released quickly.

v0.20 - change to developer-secure.symbian.org, to fix Bug 3627 Also move the point at which downloadpage.html is saved, in order to get all of it for debugging

v0.19 of downloadkit.py - removed the "-p" short form of --password, to avoid confusion with "--progress" if the first minus is omitted - add support for "Do You Feel Lucky?" downloads, which included changing the version check - added report_to_symbian() which logs the way that downloadkit is used and the success or failure - added --nopublicity to turn off report_to_symbian()
