Various cleanups for tarball support

s/tarball/archive/
query config rather than maintaining a list
default all archive support to off
use changeset nodes rather than manifest nodes
use web:name for archive name
don't use rev number in filename, it's not portable
refactor manifest lookup bits
use finally: clause to delete tmpfile
