expo: Begin implementation of a text editor
It is useful to be able to edit text, e.g. to allow the user to edit the
environment or the command-line arguments for the OS.
Add the beginnings of an implementation. Future work is needed to finish
this: keypress handling and scrolling. For now it just displays the
text.

Some ideas for future work:
- Default menu item and a timeout
+- Complete the text editor
- Image formats other than BMP
- Use of ANSI sequences to control a serial terminal
- Colour selection
