Drones need to "sweep" map and pester enemies

[gopenshaw]

The drones wait until they have sufficient numbers, they they barge straight down the middle of the map. In a lot of matches, there were enemy drones that were unprotected on the edges. Picking these off is very valuable.

My idea is that we will constantly have some number of drones "pestering" the enemy. They can do a swam early but have very defensive micro. They can also sweet the edges of the map and destroy miners that are not protected.

With the new pattern, I am thinking that pestering would be an Order, and sweeping would be a Job. Sweeping is something that we would want one or two drones to do. Or maybe I am just introducing unnecessary complexity.

Priority orders allow a subset of drones to take on a special task. If scrimmages reveal that we need some new priority orders, we can open an issue at that time.
