(svn r8661) -Fix: [depot windows] Enlarge the blocks in the depot window if a sprite is too big to fit (ships and aircraft only)

-Codechange: depot windows default now makes a 1x1 matrix and resize the window by block size*number of blocks
   This will make less vehicle type specific code and easier to read resizing based on sprite sizes
