Minamp 1.4: faster connecting

- Remember the connection that worked and try it alone first next start
- Prefer plain HTTP on the home network (each TLS handshake costs seconds on a
  600 MHz phone); new setting "Encrypt at home too" to keep HTTPS
- Try secure addresses one at a time instead of in parallel, so they don't
  all time out together
- TLS 1.2 with session resumption: reconnects skip the full handshake
- Cache certificate chains already verified; changing the trusted roots
  clears that cache and all TLS sessions
- README: updated connection order; test: session resumption check and
  HandshakeProfile
