Crusade changes v2

I'd like to explain my reasoning first.

Crusades are usually very lopsided and revolve around conquering Middleland mine fast, then maintaining it. The other two stones are hardly ever used and they aren't needed as well, so you get an event in which usually one city overruns the other and they look practically the same all the time. So I'd like to add these changes:

1. The buildings within the screen of the wwe and clops Ares stones get powered up. Mana collectors collect mana 50% faster, arrow and cannon towers deal 25% more damage and have 1 more tile range, detectors can detect the whole screen. This is to encourage the weaker city to build and mantain these spots.
2. GMG can reflect damage like a tier 9 mob and summons units according to the damage dealt to it in 1 min. For 1000 or less it summons a minor unit, for 3000 to 5000 an intermediate unit, for 5000 or more a golem/knight. These summons appear in guard mode around the gmg
3. Sade max time is reduced by 30 min
