Fix 301 redirects in the UrlBuilder class

• http scheme redirects to https
• Mobile website (m.last.fm) redirects to www.last.fm
• Localized hosts redirect e.g. www.lastfm.de to www.last.fm/de
• New localePath() function has been added to handle the localized base path since the library was localizing using the host before. This is not an official fix, but upstream is pretty dead.
