manager/qubesmanager/settings.py
Marek Marczykowski-Górecki 7a5c304c1e
Merge remote-tracking branch 'qubesos/pr/95' 
* qubesos/pr/95:
  Revert last and removed pylint disables
  Added BaseException
  Show updates pending while running domain
  Fix search coherence when adding a domain
  Last no-member
  Try with disable=no-member
  Another try for travis
  Disable no-name-in-module
  Fix pylint warnings
  Fix very unlikely case when user right clicks the VM in the exact moment he deletes it.
  Don't close the settings window if something failed when renaming e.g. the VM name already exists
  Revert "Since __lt__ methods are safe, is not needed to stop and reenable sorting."
  Added standalone VM's to check_updates() Also added an initial call when creating the timer, most users will look for updates inmediately after start the manager
  Since __lt__ methods are safe, is not needed to stop and reenable sorting. It causes a short freeze of the main window when reenabling, so better removing it.
  Added try/except for all __lt__() methods since some VM could be deleted before the signal is received and handled.
