Minamp 1.5: Galician interface

- Interface in Galician by default regardless of the phone's language, with
  English selectable under Axustes -> Idioma; switching rebuilds the screens
- All text in tools/strings.py (key -> English, Galician), generating
  res/values/strings.xml (gl) and res/values-en/strings.xml; layouts now use
  string resources
- util/Tr.java: translations for the network and Plex layers, which can't
  read Android resources (falls back to English in desktop tests)
- net/RefusedException: distinguish "server answered but refused" from
  connection failures
- The connection log stays in English for troubleshooting
