all whitespace. This allows for some mild code cleanup. It's also declared in the PBD namespace now. sfdb-v4 implemented. Instead of fields that go across all files, there is now just one tag field where you can enter comma delimited tags. Searching for tags to follow soon. I recommend trashing your current ~/.ardour2/sfdb file. git-svn-id: svn://localhost/ardour2/trunk@1182 d708f5d6-7413-0410-9779-e7cbd77b26cf
