Added property non-default to KeySignature (issue 300840043 by address@hidden)

[panteck]

Reviewers: ,

Message:
This patch adds the non-default property to the KeySignature grob.  It
works identically to the non-default property of the Clef grob.

Description:
Added property non-default to KeySignature
Added the property non-default to the KeySignature grob, and updated the
grob definition to indicate that it works for both Clefs and
KeySignatures now.
