make changing default coin supply setting possible

[GoGi]

This patch adds an add-on. If activated, players can choose the default setting, coins off or coins on, for newly built military buildings.

What is missing are suitable graphics for the new progressbar, maybe a coin and a crossed-out-coin or something like that.

divan, can you have a look if the patch does work?

[Stefan Kriwanek (Divan) (dev-stefankriwanek)]

I have changed some things and made an own patch that seems to work.
GoGi, you haven't sent your AddonAllowCoinSetting.h. Do a "bzr add your_new_file" next time ;)

I just saw, my patch still lacks:
- a savegame version increase
- a tooltip to the new button in iwMilitary that represents the current status. I found it difficult to find a shorter term for "default coin distribution on/off"

[Stefan Kriwanek (Divan) (dev-stefankriwanek)]

Full and final version, it works and is tested. Instead of a progress bar I added the same coin button to the military settings (if addon enabled) as in iwMilitaryBuilding and as GoGi proposed. I also had to increase iwAddon's height a bit (there's not much space left now...)

GoGi, thanks for your code!

I merged the addon from Johann (see branches)

perhaps you can adapt the other one so you can switch the setting ingame (like your patch)
