[Freeciv-Dev] patch: change terrain rulesets to new ruleset format

[Jeff Mallatt <jjm@xxxxxxxxxxxx>]

This patch changes the terrain.ruleset files to conform to David's new
ruleset format (and, of course, adds the code to handle the new format).

I uploaded the patch to:

ftp://ftp.freeciv.org/pub/freeciv/incoming/new-ruleset-format-for-terrains.d
iff.gz

To convert the existing terrain.ruleset files, I adapted David's
conv_unit_rs.pl script -- if you want it, you can get it here:
    ftp://dumuzi.codewell.com/pub/prj/freeciv/conv_terrain_rs.pl
(This requires David's registry file parser module, which is at:
    http://www.mso.anu.edu.au/~dwp/freeciv/misc/fc_registry.pm
.)
