Feature/pending failed message icons

[cafalchio]

This commit is a fix to issue #150 and also adding icons to show pending and failed messages.

I think this helps towards Issue . But we can still send / spam messages (leading to failures) and its not really fix.

Further more to this, if you send a message before the fee estimation is finished. You can get toast errors.

Also, in some sates we get messages that have none of the status symbols:

See my comment below, it might address this.

Another discussion point:
If I try to send a tx and fee estimation is not complete. It just sends the tx and fails it.
Leaving the message text still in the input.

I think this is going to be a v0.4.0 addition.
I don't want to rush this through just because we have a deadline with v0.3.0

Do you think we need to wait for estimated fee before letting the user to click send?

Thats how it currently is on staging.

I think there is a better solution somewhere.
Even if we don't wait.. we shouldn't do the following: fail, not retry sending and leave a failed message bubble.

100% agree.
