add gridsize to the hud configs so that the player won't have to find out which gridsize the artist used to not get the annoying snapping panels as soon as he clicks one. Unsure about luminos gridsize atm, so setting it to default (0.01, has snappy panels here...). Also add a menu_restart to the end of each skin config so the menu dialog values are enabled :)
