William Wilgus 80c3b84e08 lua Add scrollable stack traceback WIP
lua currently splashes a stack traceback on error
for deep tracebacks and especially on devices with smaller screens
this leaves out a lot of vital information

in the past I have resorted to splitting the traceback string or
even saving the return to a file

This patch provides a scrollable buffer with rudimentary text reflow
to allow you to read the whole traceback string

Upon traceback if you press nothing the screen will display for 5 seconds
If you press OK or CANCEL it will quit immediately
PREV/NEXT scrolls the list on button press timeout is disabled

lua now provides rb.splash_scroller(timeout, str)

example script provided too
