Typeset the lines according to these rules (in order of subjective significance):
* words that fit on the screen but would let the current line overflow are placed on a new line instead
* " | " always forces a linebreak
* spaces are included, except when there is a linebreak anyway
* words with more characters than fit on screen are just chopped up, filling the lines as full as possible
* don't bother typesetting more lines than fit on screen
* if we are on the last line that will fit on screen
Digilines is probably used by most people in its entirety.
I've retained the ability to disable inventory, rtc, lightsensor and
LCD by the minetest settings "diglines_enable_rtc" etc.. If set to
"false", these components will not be loaded. It is assumed by default
that these are enabled.
In the conversion the digilines_lcd:lcd node was renamed to
digilines:lcd (same for all the other nodes). To retain backwards
compatibility I've provided aliases for each of these nodes.
