Move decorator editing window within attribute editing window

[noah-schechter]

Current
Users configure the decorators for each attribute in a separate part of the Manage page from where they configure the corresponding attributes.

Proposed
I think users should configure decorators within the editing modal for the corresponding attribute. Is the issue here that that would crowd the modal?

There are four reasons why I didn't do this, three UX and one practical:

• I suspect users will often want to edit decorators in bulk; having to go individually into each attribute and re-specify attribute values feels like a pain. In my mind it makes sense to think about all the decorators together.
• I also think that it would indeed make the editor window crowded.
• Decorators should be a rarely used feature; to the extent possible, I think we should remove them from the regular user flow.
• It'd mean that we'd need to create popup modals for editing core attributes, which is a bit of a pain; it'd also require refactoring the Phoenix form, which would be annoying.

Closing for now but reopen if this explanation is not compelling and/or you feel strongly that it needs to be in the attribute editor.
