Creates convert-ly rules for flag syntax changes (issue 5050046)

[mtsolo]

Reviewers: ,

Message:
Hey all,

I think this convert-ly rule should encapsulate all changes
precipitating from the flag grob.

Please let me know if I have the version number wrong - I'm still kinda
fuzzy on what version numbers to use for these rules.

Cheers,
MS
