Don't let designate check total cost before doing anything

Don't let designate check total cost before doing anything

desi() ran the designate code twice, first for adding up the cost,
then for changing designation.  However, the checking pass already
changed the sector when that cost nothing.  The checking pass also
suppressed messages.  There was at least one message that never got
printed because it was suppressed in the checking pass, and the
condition for it was no longer true in the changing pass, due to the
premature sector change: when a deity changed a non-coastal sector to
harbor or bridge head.

The total cost check is of limited value: designate costing money is a
bad idea, and the stock game has no such sectors.  Not enough value to
justify keeping and fixing this disgusting mess.  Remove it instead.
