Updated to improve support for OctoPrint use

The pe_lmsg and pe_rmsg commands have been superseded by pe_imsg, which takes up to 20 characters and will be displayed split 10 chars left/right as appropriate, or just the first 10 characters on the right in 'busy' mode.

A new control pe_bcfg has been added to control how the button behaves; giving options for M112 (reset/emergency stop) and other uses. As well as Octoprint-friendly pause/resume in busy/idle states.

See the README for more, it has been updated with the new commands and an example of how to get progress display from Slic3r. Getting 'native' OctoPrint progress display is tricky and I really need to write a plugin to handle that.

The code is a bit smaller too thanks to some refactoring and learning to better use progmem for fixed string functions.

I've finished work on a v2.0-dev branch to add more button functions, resets and sending OctoPrint action commands for pause/resume. Plus changes to how the arbitrary text system works. Hopefully I can get progress monitoring from OctoPrint working too.

I even reduced code size and memory use 👍

It builds, but is completely untested.. I'll test it soon and publish once I have worked the OctoPrint setup out..  

Got some exposure! here and in the Duet forum.
Thanks to everybody for dropping by, and thanks for the comments here and elsewhere. Much appreciated!

Fitted to my Printer and powered for a whole week now, I'm pleased to say it's still working, responding, not hot or crashing . I'm also happy with the functionality, no software changes occur to me.
