Just to be clear on what changed:

• I added mutalisks building and control(alongside the spire ofc)
• I added some error prevention
• I made some check for close units so its doesn't retreat for that(we should win base trades vs anyone that don't float buildings) can be troublesome if you don't find all buildings so this needs improvements(reverted)
• I changed building placements so it doesn't block mining
• Change step back to 4
• Cleaned unused stuff
• Fix a bug that prevents canceling also improved on it(found the way to make it work everytime)
