The second argument of minetest.settings:get_bool is the default value (for when the configuration value is not set). Remove the superfluous `or nether.NETHER_REALM_ENABLED` which rendered the config option useless, because it always forced the variable to true.
32affba6 re-registered stairs which have already been registered 20 lines earlier in the code, and registered them as "brick" causing the netherbrick stairs to replace Minetest's default:brick stairs. The rest of 32affba6 was already unrolled in 7a0e52da, but the stairs bug remained.
Currently proof of concept: Removes wormhole colour from .png texture and specifies it through MT API instead. The post_effect_color may call for registering a separate node per portal colour.
Palette 0 will have to be the traditional portal magenta (instead of 0 being black) for map compatibility with mod when colour was in the texture and not param2.
While it's rather cute having portals that share parts of their frame with other portals, the way the nether mod implemented portals means a node being part of more than one portal enables a family of bugs.
Igniting a portal now extinguishes any portal that was using nodes now taken by the newly ignited portal.
Allows dev and testing/debugging to focus on one (shape or behavior) without getting mixed up in the other, will also enable different portal shapes later on. Other adjustments:
* Reuse/reignite an existing portal or portal frame if there is one at the remote destination, rather than the area being overwritten by a slightly offset portal schematic.
* Create remote portals in a matching orientation to the local portal.
* Preserve player position & facing relative to portal when traveling through wormhole (even if portals are at 90°)
* Players no longer bounce several times after teleporting
* Player is not teleported until after the portal at the other end is confirmed/built
