v1.1

• fixed bug where gathering workers would drop resources off all the way back to the queen unnecessarily
• fixed bug where the bottom-right idle worker button would sometimes not detect idle workers (specifically if they depleted all nearby resources of a certain type)
• fixed bug where double-clicking on a unit that overlapped with a building (e.g. farm) would not select all visible units of that type
• fixed bug where worker ants would overlap when gathering resources
• improved late-game AI resource allocation, plus normal and hard AIs now research fireball
• updated map a little bit with a new mini pond tile

thanks for all the support so far!
