Add support for fwupd

Closes #123

Something I noticed is that this introduces a significant lag when first opening the page. There are probably some operations that need to be made asynchronous from the view construction

I'm getting a real big lag when first opening the System plug again :(

[davidmhewitt]

@danrabbit ah, oops, I wonder if that's related to my merge earlier. Does it go away if you install switcheroo-control. It might be timing out waiting for that.

[danirabbit]

@davidmhewitt ah yup, I think that's it. Created #171

[davidmhewitt]

I'm happy with the code, but I have not conducted any testing. Nice work @meisenzahl !

[meisenzahl]

@davidmhewitt thank you for your reviews and constructive feedback.

[danirabbit]

From the testing I've done, I'm happy with this as an MVP. I think we can wait until follow ups to iterate on the design and add features. But this does the thing as far as I'm concerned:)

I created some issues:

• Add detail page for firmware releases
• Show useful information during firmware update
• Add cache for firmware updates

Feel free to create some more if I missed something :)
