Minamp 1.3

- Fix NoSuchMethodError on Android 2.x: Dalvik before 4.0 can't link Object
  methods (toString/equals/...) called through an interface. Patch the bundled
  Bouncy Castle (tools/patch_bc_dalvik.py) and our own CertVerifier, and make
  build.sh fail if tools/scan_dalvik.py finds any such call
- Treat a manually entered private address (10.x, 172.16-31.x, 192.168.x,
  .local) as home, so LAN servers that allow access without sign-in work
- Send Plex client headers on media requests (files and transcodes)
- Explain a 503 on a file as the server being unable to open it (drive or
  folder not available)
- Connection log: home/away, token presence, Plex's file check and a direct
  file request in the streaming test
