diigo-cache: webkey page logs in with the password manager

/cache/ without a fragment is now a login form: petname
(autocomplete=username) and cache id (type=password,
autocomplete=current-password), the shape password managers fill from
the entries the save button makes. Its inputs have no name, so a native
submit (script failed) sends nothing; the key stays in memory, out of
the address bar and history. Home links to it.
