New toot scope from "messages"

[bashfulrobot]

First off I have to say by far this is the best Mastodon client on mobile.

Describe the solution you'd like

When you are in the "Messages" part of the application, starting a new message from there, it should be scoped to "direct" vs the default.

Describe alternatives you've considered

Change the scope manually as it is done today.

Additional context

I find this might help people scope messages as intended in a safer way. Especially those migrating over from Twitter.

Thank you!
