first attempt at making unit collision.
Placing buildings actually works now.
TODO: Fix the origin and drawing of the units a bit. Also make the house transparent
Merge remote-tracking branch 'origin/master'
Removed the old client. Fixed the building image better. Actually shows if you can't build. TODO fix the positions.
Working on integrating the building buttons now
More work on group pathfinding. Still unfinished.
Added some check. Working in the HUD
Some start of resource system, switch from random collision map to random entity map. Fixed pathfinding (?).
