Code review comment for lp:~fossfreedom/debian-cd/ubuntu-budgie

This merge looks fine to me (but I can't merge it). The only piece that actually affects the linked bug is to set HIDDEN_TIMEOUT=2 so that if no key is pressed (in accessiblity scenarios) then the system will continue to maybe-ubiquity (the panel that lets you choose between Try and Install). It *will not* always boot to that panel, if a key is pressed when the accessibility icon shows you will still have the option of choosing exactly how you want to start.
