Include Building Hotkeys For Norse Infantry in Default Keybinds

Bump!

This should be moved to the section bugs, because if you select a norse melee-unit, and place ur mouse over the barrack button, you'll see the 'Shortcut 'B'' in the tooltip, but doesn't work.

Beware though, if the devs fix this, don't forget that the keys 'A' for Attack Move and 'D' for Defensive are already used Maybe there's the S to stop the units too? Would make sense...
