DRAFT: lqtop keyboard input API

Browse Source 
This is a draft attempt at working out what keystrokes and
functionality lqtop could gain for the beleaguered BOFH.

Presently functionality is stuck on:

* Capturing a screen resize event doesn't work
* Needing to be able to send a starting row to the bus
* More bus messages in general
* BOFH ignorance has to how to message the other thread
