Title: Uninstall all button w/ confirmation and language strings

@ExtReMLapin said he doesn't know HTML and could not add the confirmation. I cherry picked his commit and added the rest in my own commit so everything is under one PR but still giving some credit to him.

The language strings will need to be uploaded to Crowdin for translation and rebuilt before the proper strings will show in-game.
