Bloks 2.8.1

A stop right after sending is honoured, and restores in a row both go through.

• Stop works from the first moment. A conversation shows "working" as soon as you send, but the engine starts a little later, once the turn has what it needs. A Stop, or Esc, pressed in between was lost: the turn started anyway and ran on. It now ends there with a line saying it was stopped before the agent had started, and whatever was waiting behind it goes next. Redo of a message the agent had only just been handed no longer waits twenty seconds and refuses. Thanks @ashottonoyan (#272)
• Two restores in the same second. The folder a restore sets the old workspace aside in was named to the second, so a second restore inside that second failed, and its note made every later start fail the same way. Each restore now takes a name of its own, and a note already stuck on a taken name is applied beside it. Thanks @ashottonoyan (#271)
