PhraseLens v0.5.3 — No more stall after a capture

Fixed

• The beachball after a screenshot capture is gone. A crop holding no text raised
  the error alert, and that alert arrived while the main window was still coming back
  from being hidden for the capture — so its backing surfaces were allocated and
  synchronised against a render server that was already rebuilding the window behind
  it, and the main thread sat there. Sampling a capture over a blank region put 929 ms
  on the main thread, 668 ms of it inside a Core Animation commit; the same capture
  over text cost 138 ms, because that path raises no alert. An empty crop is an outcome
  rather than a failure, so it now takes the route an empty selection already takes — a
  line in the status bar — and the same capture costs 103 ms.
