[Freeciv-Dev] (PR#13355) Percent defense bonus

["James Canete" <use_less@xxxxxxxxxxx>]

<URL: http://bugs.freeciv.org/Ticket/Display.html?id=13355 >

This patch changes the defense_bonus values given in terrain.ruleset
into added percentages, and allows for negative values as well, for
defense penalties.

I'm not sure if this is the right way; presently veteran defense bonuses
are given as multiplied percentages, so perhaps these should be set to
match.

I would like these values to be signed though, so I can wedge in my own
alternate combat system, based on 6 sided dice. :)

This patch compiles, but has not yet been tested.
