Changed 'publish' to 'sf-publish' to only publish the zips, not all logs. Changed behaviour so that 'sf.spec.package.src.enable'=false stops the source repos from getting packaged, but not the RnD ones (which are extracted again in platform builds)

source syncing ftl - Added 'sf.spec.sourcesync.archive' preference to do 'hg archive' instead of 'hg sync'. If set and the repo sync is s'posed to be synced by tag it still does the slower clone+update behaviour.

platform build - added 'sf.os.compile.iterate' variable to iterate though the main targets rather than all at once to work around raptor problems with single model.

Split sf-run-analysis into bit-sized targets, which can run in parallel to reduce the post-build time on a platform build.

catchup merge

minor fix - creation of 'generated' dir for caching files.

raptor parser.pl - adding XML::SAX perl modules (public domain code - http://www.saxproject.org/faq.html) so we don't have to patch up every single build machine.
