Previously, Digilines used concatenations of X/Y/Z coordinates into
strings as keys to check for repeatedly visiting the same node during a
graph search. Replace them with integer keys generated by
`minetest.hash_node_position`, which should be more efficient.
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.
