Summary: Common line-drawing function

Initial Comment:
The Broken Sword 2 engine has always had a line drawing
function. It would be nice if this could be made a
common function so that other engines (e.g. GOBLINS)
could use it as well. I just rewrote the function to
make this kind easier; the patch simply moves that new
function.

Since each engine has its own ideas of how to draw to
the screen - particularly if they handle screen
dirtying - the function works by using a callback to
plot each individual point.

The patch changes the BS2 engine to use the new function.

I'm not sure if util.cpp is the appropriate place for
it. It doesn't fit in the graphics directory, though,
since it doesn't actually do any drawing on its own.
