[Freeciv-Dev] (PR#14689) Resource patch, keeping savegame compatibility

["Jerome Plut" <Jerome.Plut@xxxxxx>]

<URL: http://bugs.freeciv.org/Ticket/Display.html?id=14689 >

Here is a new patch (vs. SVN trunk) to handle terrain
resources separately from specials. I've added a bit of code in
savegame.c to preserve savegame compatibility:
 - the order of the modifications bits (road, fallout, hut...) is now
   saved into the savefile,
 - when loading an older savefile, default order is used, and there is
   an extra part to take care of special_1 and special_2.
Again, this changes almost nothing for gameplay, except that it
allows to define more than two different resource types for one
terrain type. The patch is quite big, but a large part of it being due
to some renames, maybe I could split it in two parts (there are not
much code changes). The motivation of this is that it is a (small)
step towards defining infrastructure (and so on) via ruleset.
