Request for patch:   Ocean numbers
------------------

For some time I was convinced that there are no inland lakes in the 
Freeciv-generated maps.  However, I recently saw an example to the 
contrary, a small inland lake.  A stark example to the contrary is 
provided by Jason's savegame in this thread.

Unfortunately, some of the AI code assumes that a boat can get to any body
of water.  Of course such things can be tested by PF every time the
question arises, but it is much faster to do it once (almost) and to 
calculate and assign ocean numbers.  Positive numbers are reserved for the land
continent, so we can use negative ones.  "Diagonally" connected oceans 
must have the same number -- since the boat can go diagonally.
