Confconsole - add button to support "login and launch confconsole advanced" #1562
Description
This issue is somewhat a combination of 2 previous issues (that I'm closing and replacing with this one); namely #1463 & #1482.
We won't be adding a "shutdown" or "reboot" button to the so-called 'usage' screen (i.e. the default Confconsole page that shows before logging in), but it would be good to make it super clear how to access Confconsole's advanced menu.
I suggest that we add a new button to the 'usage' screen (currently there is just one "quit" button in 'usage' mode, in 'normal' mode that is replaced with the 'advanced' button). Something to the effect of "quit, login and launch Confconsole 'advanced'".
