Update - Catapults, Battering Rams and More

Just uploaded a big new update.

Seige units (catapults!), crossbowmen, building upgrades. Greatly improved how ranged units work.

A big balancing to reduce the difficulty of barbarians. Town halls can defend themselves - all sorts of buildings now hold defensive capabilities, making seige units all the more necessary.

And, of course, fixes for endless bugs!
