Disable the admin toggle and delete operations from the current user, to avoid accidents.
(cherry picked from commit b0f5ac6df5d31f612dc833a88cfca8936c4137d7)
Adds a new javascript parameter that holds the webroot of the app. This
allows the the javascript calls to properly identify that they're
running in a subfolder/different webroot and direct their queries there.
Direct binding only works for elements already in the DOM, delegated
binding works for all elements that match a filter even if created after
the DOM is fully loaded.
