Concealment etc...

added concealment and visibility mechanics

must have los to a unit and have it be within sight range for it to appear visible

los can be blocked by hills or other units

units in concealment, ie in the woods for now, have sight range to them reduced

redid entire basic soldier movement and in combat coordination, some bugs still but better and more performant than before for the most part
