Delete - Overboard and Bygg Bilar Med Mulle Meck

The game Overboard! is just the European title of Shipwreckers! and is already an alias of Shipwreckers!

The game Bygg Bilar Med Mulle Meck is simply the Swedish title of Gary Gadget: Building Cars. Bygg Bilar Med Mulle Meck should be added as an alias to the Gary Gadget page.

@bobafettjm: Done.
