Release plasma-angelfish 1.0

This is the first release of Plasma Angelfish since its development has been taken over by the new Plasma Mobile team. Compared to before, several features have been added:

  • tabs can be closed
  • web search
  • in-page search
  • sharing pages
  • history based completion
  • Mobile pages are requested if wanted
  • context menu
  • popup blocker
  • basic downloads
  • configurable homepage and search engine

On the technical side of things, Angelfish has been ported to the current QtWebEngine (as of Qt 5.13) and now uses Kirigami instead of Plasma Components.
