Started workon on placment, shown if clicked on Help in the main menu.
Removed Ship Icon
Tried to get a grid of buttons in placement, but not yet working.
Tried more things with the placement grid buttons, but still no results.
Fixed all errors, but still just a blu screen.
Fixed so tiles are showing as a grid in Placement, and placement is reached by clickeing Help in the Main Menu.
Merge branch 'feature/placement' into develop
