New super secret developers shortcuts

We are now providing the following developer shortcuts:

• The key sequence X, X, X, A toggles the "advanced user mode" for the currently logged in user. Performing this sequence as an advanced user will switch it back to the "simple user mode" (the default).
• The key sequence X, X, X, H toggles the "show hidden pages" option for the currently logged in user. Performing this sequence while already viewing hidden pages will switch back to hiding hidden pages (the default).
