mb2q: Add option to sort input mbox by subject

When picking up an mbox from an archive like lore.kernel.org,
it isn't uncommon that the mbox has the emails in a random
order (most likely the order of delivery).

After processing, the resulting mbox will be in the same random
order, which doesn't really help when trying to do a "git am"
with it...

Add a new option (-S) to sort the source mbox by subject (which
hopefully fits most of the patch series) before processing it.
