Better manual painting of zone borders

[Apthorpe]

As anyone who has played Shadow Empires knows, manually painting zone borders can be a pain. It's not so bad when it's just a few hexes, but sometimes you have a lot of area to cover, and you're going to have to spam single click over and over. Something like a click-drag to paint the zone border would be ideal. Another feature which would be welcome is if there was a way to attempt to auto-grow the zone border by 1 in each direction. These two additions would be a welcome mitigation to the tedium of manually painting zone borders.

If you expand the new zone to the next zone borders, effectively leaving the old zone cut-off, the game will automatically incorporate that territory into the the new zone. It took me a while to figure that one out, but it does work and is fairly intuitive.
