Create red migrate buttons for features and editing credits

[LegalizeAdulthood]

I love the new 'Migrate' button next to the text features line and that the 'issues with text credits to migrate' link for a series now lists issues with editing text credits that have not been migrated. These are great additions!

Can we add buttons to the edit page for an issue with red text to remind us that editing and features have not been migrated?

I suggest a red text "Migrate Editing" button to the right of the existing "Edit Issue Fields" button. It is the same as clicking that button and then clicking on the "Save and Migrate Editing" button on the edit issue page. After attempting migration it leaves you in the edit issue fields form. This saves one round-trip to the server; always a good thing for minimizing load.

I suggest a red text "Migrate Features" button to the right of the existing buttons for a sequence, but only if no "Migrate Credits" button is present. (Migrating the credits has the side-effect of attempting to migrate the features as well.) After migrating the feature it leaves you in the edit form for the sequence. This saves one round-trip to the server; always a good thing for minimizing load.
