Melarka 0.2.20

Fixed

• The iPhone app no longer starts music by itself on a phone nobody touched. When iOS woke
  Melarka in the background, the "when the app opens" setting (shuffle favorites, or resume) could
  start music on a locked phone. It now waits until you actually open the app. Music that stopped
  because the network went, or because of a call, now starts again by itself only if it comes back
  within 10 minutes; after that, only you start it. The Android app follows the same 10-minute
  rule after a call or when the network comes back.
• Re-signing from a Mac (ios/scripts/resign.sh) now notices a locked Mac and waits for it to
  be unlocked instead of failing, and a phone that is slow to answer no longer counts as "no
  Melarka on the phone". It also installs a new release within 15 minutes, instead of at the next
  weekly renewal. When Xcode is not signed in to an Apple ID, its notification says so, instead of
  only "build failed".
