[mod] 3d vector class [wip][vec3d]

[burli]

This mod adds a class for 3d vectors to Minetest. The functions are inspired by PVector from Processing and Unity Vectors

https://github.com/MarkuBu/vec3d

Pre release. No licence yet. Doc not finished, not fully tested

Hm, most of the methods are already implemented in Minetest builtin: http://dev.minetest.net/Vector_helpers. Not objects style, but always available without additional dependency.

I know that. But objects and the convenience of normal operators are reasons for me to make this mod. Another reason was that I made a PR to add new functions to the builtin vectors that was never been added. Was tired of waiting

we always need precise vectors!
