Better download feedback / queue view

[DanielTerletzkiy]

Describe your suggested feature

Example:
I go to a movie/ series and click on "download"

Current Behavior:

• The button seems to get pressed, and you need to wait for a toast message to tell you if it is doing something, this can take a few seconds.
• After that, the download icon appears, assuming the download queue is currently empty and it taking new things.
• If you go to the downloads section, the queued but not yet started downloads will not appear, so you don't know if you even put them in queue or not
• If any download before that fails, you will not know, and you need to search everything back up and hope that it does it right this time...

Expected Behavior:

• When the download button is clicked, it should show something like "In Queue" or something similar
• There should be a subsection in the downloads section where you can see the download queue
• One should be able to modify the queue (remove and move items, etc.)
• See failed items that were in the queue

Other details

As of now, the download feature seems to be held together with sticks and Duct Tape and fails when you look at it in the wrong way...

This issue is definetly not solely a provider issue

Currently, on pre-version: a5582a7

Some of this is on my current list of things to do with the current downloads improvements work I've been doing PRs for lately.
