v1.3

• new unit: spider web. a light wall built by spiders that can only be crossed by your own spiders
• new: right-click when placing a building to build another one
• new: small grass tiles now contain a small amount of plant (green) resource (should reduce confusion)
• fixed: groups of overlapping units could go through buildings when spreading out (hopefully new algorithm for this is not too buggy/slow!)
• fixed: when ladybug died, it could drop its food tile not at the closest available spot to it
• fixed: tile directly above queen's right half was inaccessible
• fixed: when easy AI started in the bottom-left corner it never built anything

this release also introduces a new building type, spider webs. these are lightweight walls that can be built by spiders. they can help keep waves of enemy units out while letting your own spiders through, to deal with any caterpillars or mantises that might arrive!
