Made more wonders alliance aware

[Lachu]

This forum thread is about gather ideas for ally's wonders effects.
The game could be much better if players bonus is related about one's diplomatic state (especially which player He/She has alliance)

My ideas:
- ONZ will also heal allied units
- Eiffel tower will also take production bonus in each capital of allied players

In variant2 ruleset there's almost no wonders in "Player" range, but "Alliance" range is used instead.
