Improve unit readability in Japan

[Destaloss]

Playing in Japan can be pretty confusing:
Sometimes there are enemy ships hiding behind ships from non enemy Daimyos (just a little red shield under the blue number of ships)
Sometimes enemy troops and non enemy troops are added up to a total (total in red i. e. 7 when there are just 2 enemy troops)

Suggestion: Don't show other Daimyos as allied troops and just map them gray except when you are allied to another Daimyo

And it's even harder to find ships of country which you are not at war with (but e.g. plan to DoW very soon). Seas around Japan have very intensive traffic, and interesting country is often not "on top".

I guess the way troop numbers are added together just needs some regrouping.
