Generalized effects for the spy escape teleports

[danau]

I would like the "spy escape" effects to be customizable by the ruleset. Some benefits of the feature requested here are:

• Units like "marksman/snipers" can also use an escape-to-nearest-city-or-base effect after attacking

• The ruleset can decide if spies teleport to the capital, their homecity or the nearest city after completing some action

• The ruleset can also specify that defeated diplomats have a chance of escaping (to the capital or nearest city)

• We no longer need "Escape" and "non-escape" versions of the diplomatic actions

Descriptions of the effects I was thinking of:
