Restore context in deny() page
Now that we know when the sidebar is doing the access checks we can
safely construct a new context in deny (without having to worry that
it will try to do more access checks that result in deny, which will
call for a new context... etc).

tinyMCE.addI18n('en.example',{
desc : 'This is just a template button'
});
