Desktop: Desktop App: Add a download progress bar at the bottom of the screen

[mattermod]

There is currently no indication to the user that after they have clicked on a file to download, and picked the download location that the file is actually downloading.

Proposed design:
https://projects.invisionapp.com/share/YDMY3VHWKTA#/screens/308612367

The download bar can be reopened by going to “View > Downloads” if there are downloads to show.

Hi, I am interested to take this up! Can I take a look?

[esethna]

@laxmy, apologies for the delay. Absolutely you can take this! Let us know if you're still interested and I'll assign this to you and remove the "Up for Grabs" label

[laxmy]

@esethna Thanks. I would like to give it a go. Please assign it to me.

[esethna]

@laxmy you got it! Let me know if you have any questions. You can also ask our desktop devs if you have any questions at https://community.mattermost.com/core/channels/desktop-app

[esethna]

@Willyfrog can help answer any technical questions. Once you've had a chance to dive in we're also happy to review your proposed approach before you get too deep into the coding

[laxmy]

Sure thing. Will get back to you or @Willyfrog once I wrap my head around it

[esethna]

@laxmy are you still interested in taking this on?
