This PR repurposes the DownloadView into a Loader component of a browser tab and is displayed when:
1. a new downloads tab is opened or
2. a new tab with the link status://downloads or finally when
3. the ShowAll button has been clicked.
You can open any number of Downloads tabs
When you open a new tab and type in status://downloads the title will remain as 'New Tab'
fix: add localization
