Relative templates for walk/run speed

[elexis]

​http://trac.wildfiregames.com/changeset/18025/ps/trunk/binaries/data/mods/public/simulation/templates/units/gaul_champion_fanatic.xml added 34 run-speed for naked fanatics, which is faster than everything else while it should be slightly below the cavalry walk-speed probably.

Furthermore slow walking spearmen infantry champions have a much higher run speed than the fast walking swordsmen infantry champions.

These inconsistencies should be cleaned, future mistakes could be reduced by using relative templates (op=mul and op=add).

In 20230:

Use relative templates for unit speed. No significant value change. It makes balancing easier and will permit to change the speed of all units by changing one number. Refs #4352.

I think we can close that. A next step would be to adress the inconsistency of current values:

• fixing the cs - champ - hero consistency (no opinion from my side, perhaps making all equal)
• fixing the cav - inf consistency (keeping more or less the same ratio for cs, champ, hero)
• fixing the internal consistency (no opinion from my side, light units are intended to be faster, but that would make ranged units too powerfull...)

So the balance guy should take care of that.

Thanks for the patch!

As you pointed out, there are some inconsistencies, but probably no need to have an open ticket for that, so agree to close it.
