TapQueue server and station 0.10.0

Changed

• Each queue needs its own name (whatever the case), at most 127 characters and without tabs or
  line breaks. PCs know their printers by name, so two queues with one name could never both be
  added. If you already have two with the same name, rename one.

Fixed

• Crash reports and rejected tray sign-ins, which need no sign-in to send, each added a line to
  the activity log, so anyone who could reach the server could bury it and fill the disk. The log
  now takes at most five of each a minute from one address; crash reports themselves are still kept.
• Job and user names longer than the 255 characters IPP allows are cut to that instead of being
  stored and logged whole.
• PDFs are counted one at a time, so several large ones arriving together can't use up the
  server's memory.
• An admin console sign-in as a local user who has no console password took less time to refuse
  than a wrong password, which told a guesser which users have one.
• Station: an answer that isn't the server's (a proxy's error page, say) no longer ends its
  heartbeats until the next restart, or stops the station on a tap.
