Previously, ServerEnv created a player instance before they're fully initialized.
This commit moves all initialization steps and callbacks into TOSERVER_CLIENT_READY
^ which includes StageTwoClientInit for player loading or creation
`IShaderSource` was designed with the idea that if you want a shader,
you must want it for a node. So it depends heavily on being given a tile
material and the node drawtype. But this doesn't make sense neither in theory
nor in practice.
This commit takes a small step towards removing the incorrect abstraction.
* Add "lava flan" (.x model) smoke test
* Fix double finalize in `.x` mesh loader
* Use reserve instead of resize again
The weights are added indirectly via `AnimatedMesh->addWeight`
The currently established convention uses `NS` for "translation no-ops", i.e., it will be collected by a string-collecting utility but not be translated by Luanti at this place.
We don't want to mislead modders with this example into using `NS` for plural forms instead, breaking with the established convention and making use of automated tools harder.

BiomeGen::getNextTransitionY(y) did not guarantee the condition (y < biome_y_min)
of the next loop because the function may return the value (biome_y_min - 1).
Hence, the biome was not updated until one Y coordinate after.
We are being lax here, but the glTF specification just requires that "when the weights are stored using float component type, their linear sum SHOULD be as close as reasonably possible to 1.0 for a given vertex"
In particular weights > 1 and weight sums well below or above 1 can be observed in models exported by Blender if they aren't manually normalized.
These fail the glTF validator but Irrlicht normalizes weights itself so we can support them just fine.
The docs have been updated to recommend normalizing weights (as well as documenting the status of interpolation support).
Weights < 0, most of them close to 0, also occur. Consistent with Irrlicht, we ignore them, but we also raise a warning.
