To test:
 * use rhn-manage-channel-internal --read-taxonomy to dump a channel's taxonomy
into a file.
 * edit the file, changing any of the values (except channel label).
 * use rhn-manage-channel-internal --update-taxonomy to update RHN with the new
value.
 * use --read-taxonomy to verify that the value was changed.

So it looks like everything works *except* for updating. If multiple edits are
made to a channel's taxonomy it will accept them and update everything but the
state.

verified in dev - looks much better

now I got it to work in qa :)
