Crow updates

[Jeremy]

I would also like it if crows could not take empty cities.

And, as you might imagine, I'm fine with them dropping down to strength 3. I don't envision them as a combat threat.

If it's easy, the idea of letting them scout stacks is cool. (I've never gotten that to work with my actual scouts -- I just attack the stack, and hope they don't have a scout of their own, right?)

Just to clarify, the scouts scouting ability was canceled from beta4.
