Queries can be marked as 'For all projects'. Such queries will be available on all projects and on the global issue list (#897, closes #671).

Only admin users can create/edit queries that are public and for all projects.
Note: this change does not allow to save a query from the global issue list. You have to be inside a project but then you can mark the query as 'For all projects'.
