Adds required android version and last update date of the app to top of the page.
No need to scroll all the way down to the download section to get this info.
Adds links to Google Play, F-Droid Archive (by IzzySoft) and Izzy Repo for the packages.
In case you didn't know, F-Droid provides more than last 3 versions but they're on another (archive) repository that most F-Droid client apps enable access to. The only online way for accessing that repo (within a browser) is IzzySoft repo browser.
Also some apps may stop getting newer F-Droid builds (mostly because they somehow stop being 100% FOSS/FLOSS). In that case, it might be possible to find a newer version of the app -- built by the package author -- on Izzy Repo.
