Allow switching accounts when replying to a comment

[lemmygod]

Is your feature request related to a problem? Please describe.

When replying to someone, I don't know which account I'm using. This can be jarring if I have a nsfw account or for any other reason such as keeping identities contained in their context.

Describe the solution you'd like

Show a dropdown that has the default value of the account you're using, tap to select any account.

Optional: show/highlight accounts on a server that has not defederated the server where the replied to comment is (otherwise the other person will not read it)

Easier alternative:

At the very least, show somewhere which account I'm using to reply to a comment. I often abstain from replying because I'm scared to fuck up (already did once).

I did bring up in #77 that putting the avatar of the account your logged into on the post view would help show what user your logged in as. But also in comment view, putting the account switcher in the 3 dot menu there as well as changing the "post" button to "post as user@instance.com" would be good measures as well.

I don't know how resource intensive it would be to check which accounts can interact with the post and greying out the ones that can't interact, but that would be a nice feature.

This is conceptually being tested in #178

However the use of a toggle could still be important to let the user not use their anonymous account if they do choose

Would you consider applying a temporary measure until the anon view is done? Seems focus moved to #251 and that's mostly for non-logged-in users.

@lemmygod We'd unfortunately have to rewire a lot of the app to get this working because too many of the calls are done with just getting the default user data for an instance at the point of the call rather than earlier up in the chain. However, I'm actually looking into this next. As a temporary workaround, you can long press an account in the settings page and tap "Set as default" to make sure all comments on that instance are posted with the one you want.
