[AD] alert3_interlined

["Lo'oRiS il Kabukimono" <_lano_@xxxxxxxxxx>]

And this patch (*) adds the function alert3_interlined, that is like the
old alert3, but also can choose how many pixels put between the lines of
the box. IMHO this way the box looks a lot nicer...

(*) i don't know if it's correct, i never made a patch for more that 1
file... i guessed and i merged the 2 diffs... is it ok? otherwise i'll
send two separate diffs (if u intend to apply them... :)
