Added "All [] Cities get a free []" unique. (#3352)

* Added "All [] Cities get a free []" unique.

The first parameter is for city type. Currently "new" and "coastal" are supported.
"new" matches every city and "coastal" matches cities on a coastal tile.
"new" and "coastal" were added to template.properties for translation.

Upon city founding, the second parameter building is added to the city.

In civ 5 G&K, Carthage gets a free harbor for every coastal city.

* -Syntax changed to "Get a free [] []"

Supports "in every city" and "in every coastal city"

-new and coastal was removed from template.properties
-in every coastal city was added to template.properties
