Content

Implement draft support in the following way :

• When message screen is backgrounded, then the current draft is saved. It also keeps the composer mode (either Regular, Reply or Edit).
• When message screen is first composed we load the draft and delete it from the store.

This PR also introduce some refactoring around ReplyTo, so we can use the same UI logic between Timeline item and Composer.

Motivation and context

LGTM!

That's a long composer! I guess the state is expanded?

[ganfra]

I'm not sure why :/
