(dev/mail#83) message_admin - Save automatically when adding/removing drafts

[totten]

Overview

When editing a message template, there are a few actions for creating, activating, and abandoning drafts. When you perform these actions, should they be buffered in the client (until you click "Save") or should they be sent immediately to the server (auto-saving the page)?

Before

"Draft"-related actions remains local the client until saving.

After

"Draft"-related actions cause the page to save.

Comments

For comparison, in CiviMail, these lifecycle actions (creating a draft, submitting/activating a draft, deleting a draft) have action-buttons which persist immediately. Of course, with CiviMail, the behavior is almost a necessity - its aligns with how the data is stored. For Message Templates, the data-storage is different - however, this patch should make it "feel" a bit more similar.
