german mac keyboard layout uses asciitilde instead of dead_tilde

Looking at /usr/share/X11/xkb/symbols/macintosh_vndr/de (Ubuntu Saucy) one difference to the original mac os x I notice is that the ~ key (n+rigth alt) is a dead key on Mac OS X so that one easily can create the ñ character. Should maybe line 47 be changed from:

    key <AB06> { [ n, N, asciitilde ] };

to:

    key <AB06> { [ n, N, dead_tilde ] };

And then further down in the nodeadkey version add the line

    key <AB06> { [ n, N, asciitilde ] };

I noticed that here on ubuntu saucy, these definitions are for some reason additionally present in /usr/share/X11/xkb/symbols/de so they need to be changed both places.
