Build 89 Experimental

Build 89 is an experimental build that reduces unit sizes to about 70% of what they were (all taken from width, so they are more square now) but doubles the number of units (currently just doubles whatever you selected, rather than having twice as many selection dropdowns). This is an experimental change to see if the game would benefit from narrower units, as it would help certain aspects of performance, navigation, flank combats and so on. I may reverse these changes, but just looking to get some feedback on them

there are also some bug fixes in this update
