url():
  - Use https scheme to avoid 301 redirects
  - Override default QUrl::TolerantMode with QUrl::StrictMode for Qt 5.x to
    prevent overprocessing the already encoded input URL
localePath():
  - New function to return the base path of the localized website
host():
  - Just return www.last.fm since the localized hosts 301 redirect there
localize():
  - Set the path of the url instead of the host since the localized
    hosts 301 redirect to the main website with a localized path
mobilize():
  - Mobile website 301 redirects to main website, so just return the url as-is
