* Align sendstring LUTs to 9 characters wide
* Replace 0 with XXXXXXX
* Use decimal 128 for LUT size
* Align heading comments
* Add ASCII table comments
* Add missing AltGr LUTs and adjust keycode LUTs accordingly
* Use pragma once
* Correct a couple more keycodes
* Capitalise "BÉPO"
* Also clean up the default tables
* Tidy up Belgian and Norman LUTs
This makes possible to use SEND_STRING with a spanish keyboard for almost all symbols except the ones that require ALT, which are documented on the code comments.
I am not adding any documentation because the functionality is not complete until a way to specify alted symbols is added.
