[mod] Thin wrapper around lua-matrix library [matrix]

[entuland]

This mod is a thin wrapper around a lua-matrix library that allows for manipulating matrices in Lua.

Matrices are very useful to represent and combine various sorts of 3D transformations (such as rotations, translations and scaling).

This mod does nothing on its own, it's meant to provide facilities to other mods.

This mod gets used by the [rhotator] screwdriver, by the [wesh] mesh creator and by the [imaging] image importer.

Added a request about having "matrix" used by Minetest itself for its rightful role of "math primitive", so to say:
