This reverts commit 8ca3376d

Update highlighted attack nodes to show correct attackable nodes after moving. Cleaned up unused methods

Fixed issue where even though dropdownmenu wasnt displayed, it was still clickable - resulting in it preventing player from moving unit to where dropdownmenu was previously

Fixed Menu not disappearing after clicking move by adding boolean getter and setter to gameFunction. Wait button now also deselects unit.

Changed MouseHandler, GameFunction, GameState to static classes. Fixed buggy unit movement (by recoding updateUnitPosition in MouseHandler). Removed unnecessary variables from Node. Created GameState class.

 Imported new assets for stat info, new font and font sizes, and completed character info screen with updatable numbers
