lualoader: Respect loader_menu_title_align

Browse Source 
It may be set to "left" or "right" -- any other value will cause the title
to be centered.

I've chosen to position these things just inside the vertical borders,
rather than overlapping the corners. This is an arbitrary choice and easily
amendable if this looks terrible.
