Make the app root fill at least the full height of the viewport, and
make the main content grow to fill the empty space - aligning the footer
with the bottom of the page at all times.
The iOS-compatible video may not be the best quality. Add a separate quality option to accommodate people who want the best available versus the best compatible with iOS's strict requirements.
Testing with https://www.youtube.com/watch?v=YiRMs5ZhcH4 where the best quality video is 2160p and not iOS-compatible.
With best quality, the VP9 video format is used (better quality but not iOS-compatible):

Included a README note about the new quality option.
Previously angular was re-rendering the entire queue whenever any downloads changed their state. The websocket provides progress updates at a high frequency, which combined with a long download queue can quickly cause hundreds of thousands of dom nodes to be created. This results in a spike in memory usage which may persist for some time depending on browser behaviour.
Adding a trackBy function resolves the issue by telling angular which row relates to a particular download.
The arguments passed to retryDownload by the retry button do not match what the function actually expects. This causes downloads to break if a custom folder is set and also causes some settings like format and custom name prefix to be ignored.
This adds a simple download link that points to the downloaded file.
Note: This makes all files in the download directory (and its
sub-directory) available to any user.
Closes gh-26
