Bug 28882: Disable select/hide all links

We want to prevent non-superlibrarian users to remove superlibrarian
flag.
It's handled already in the controller, but needs to be done
client-side.

Here we are disabling the select/hide all links to remove the remaining
possibility to remove the superlibrarian flag from non-superlibrarian
users.
