[Do Not Merge] display more errors

[Freyert]

@terhechte thank you so much for building a mastodon client in Rust!

I'm very interested in using Ebou and contributing to the project.

As an Arch Linux/Wayland user I discovered a number of items that don't "work out of the box". Digging into them some were easy to solve, and some like wayland clipboard support were not.

Because many of the errors were "thrown away" it was a bit more challenging to discover what was going on.

👉 I would like to expose more of these errors to users to help folks troubleshoot these issues. I'm not entirely sure how to easily expose these errors to the client, so I thought I would open a PR while I try to figure it out in case there's a system you're using.

In general it comes down to changing the view_store or the state error_message. If you assign the error_message to None no error message will display.

state.error_message = do_thing.map_or_else(
//error
|| Some(format!("error message"),
 //success
 |_| None)

Need to figure out how to set the view_store.error_message.

Hey! You'd define a new item on the Action enum for the Login and then send it with the error message, like so:

If the Error Message can't be cloned and can't be send you could format it into a string first
