arcadepak: Add empty_smash.txt and empty_thexder.txt dummy files This was done in default branch in commit 9b29d654db13 but did not get into the lwtools branch. We'll probably do this differently later, but for now I'll just pick this solution. At this point everything I have spotted of useful changes in the default branch has been pushed to the lwtools branch. I have cherry-picked changes both ways in order to make a merge easier, but a real merge will probably not be useful. I did try it out and waded through merge conflicts and diff'ed the result with current lwtools branch, so I am pretty sure nothing useful will be lost.
