These were dropped accidentally, I assume, during the Configtool
template conversion. Without them the INTERCOM feature does not
compile and so board.gen3.h is broken.
Add the gen3 config to testcases and regressiontests to ensure
this does not drop again.
This #include "../arduino.h" was the only reason prohibiting
Configtool users from storing printer and board configuration
files wherever they wanted. Good reason to remove this restriciton.
This also solves a part of issue #152.
Tooltips don't size their box after line lengths, but have their
own idea on how wide to make it. Accordingly one should display
text with newlines only for paragraph delimiters.
This also required adjustments to all the board and printer
description comments. No functional change there.
This should solve issue #148.
These are no longer needed, as they're now created on the fly by
Configtool.
Also pick unique information from there over to Configtool, see
the change in configtool/addsensordlg.h.
