feat(Archive): Adds dynamic paths to browser tab

I thought it would be cool to be able to see when I was in say the
`apps_data/flipchess` folder, or some other nested folder, and have
"flipchess" be shown rather than the just "Browser" all the time. It's
not a huge or really crucial change, just a personal modification that
some people may also find useful.
