Persistent Religious Units

Missionaries, Apostles and Inquisitors get 1000000 Charges (effectively unlimited), but they are more expensive and their abilities are weaker: Missionaries cost 200 Faith and Spread Religion for +10. Apostles cost 500 Faith and Spread Religion for +11, and also eliminate 3% of other religions. Inquisitors cost 200 Faith and eliminate 15% of other religions. The Orator, Pilgrim and Heathen Conversion Promotions of Apostles are removed. Proselytizer means the Apostle removes 15% of other religions instead of 3%. ToDo: Values for spead and remove religion should be adapted to game speed. Philip of Spain needs a different ability, maybe additional Strength for Inquisitors. Mosques need a different ability, maybe additional passive religious pressure. A custom action for "spread religion every turn until the adjacent city converts" would be nice to avoid needless clicks on "spread religion" every turn.
