Klever

Implemented in branch "bridge-11450". To set user active/inactive admin should go to "Admin tools"-> "Users" -> Select user -> change "Active" -> "Save".

• Names of (preset) job directories without any visible jobs, so that activated users will see nothing at the jobs tree page.
• Marks until at least one minor right, say to observe a certain job, will be added to a new user.

I suggest to think about further considerable restrictions if necessary within a dedicated task #10828.

After all Vladimir supported the new way for granting access to new users. First of all, new users should be activated by the administrator (existing users will be automatically activated after updating Klever), then somebody should grant them some accesses either globally (this is a responsibility of the administrator again) or for particular jobs (unless some jobs already have an access for all users). Otherwise, new users won't be able to login.

I merged the branch to master in 0a0456edb.
