This may look like a rather large patch, but the changes are mostly a
reshuffling of the code to loop over all arches first, and then handle
the arch-indep packages. The cronjob has been changed accordingly.
Added new category DELETESYMLINKS, which are deleted instead of being
moved to package-cleanup. I have also fixed the arch-specific issue
with the ftppath, using parameters in config instead.
