1.1.0.beta4

Changelog

• Retain the order in which hits and hsps are returned by BLAST. In previous

  when multiple evalues were similar.
• Show error message (SystemError) if no permission to create job
  directory, or no disk space.
• By default, delete finished jobs after 30 days instead of 7 days.
• Ensure browser cache is refreshed for new releases.
• Do not show backtrace when job not found.
• Refactoring in previous beta release had broken XML and tabular
  report download link on the results page - fix it.
• Slightly modify citation line.
