Title: Remove guitar as default string set

Any instrument which does not have string data is given a default guitar-like string set.

Changed to a default empty string set.

This also allows to filter out TAB staff types in staff props dlg box for an instrument without strings defined.

Next step: similarly filter out tab presets in Instrument Wizard.
