debussy (v 5.0.v4) bug 3

1. Display a bus in the waveform viewer
2. Rename it to "foobar[1]"
3. Save the waveform signal .rc file
4. Restore the .rc file
5. Debussy crashes, because it doesn't realize that you want the signal named "foobar[1]" instead of bit 1 of the signal foobar

fixed?? in 5.0v15
