expo: Add basic implementation
An expo is a way of presenting and collecting information from the
user. It consists of a collection of 'scenes' of which only one is
presented at a time. An expo is typically used to show a boot menu
and allow settings to be changed.
One created, the same expo can be automatically presented in graphical
form using a vidconsole, or in text form on a serial console.
Add an initial implementation of the expo itself. Supports for scenes
and objects is provided later.
