Lagging behind gl-matrix

[rreusser]

As mentioned in stackgl/gl-vec2#3, some of the stackgl modules are a bit behind. gl-matrix has the following functions this module lacks. See: http://glmatrix.net/docs/module-vec3.html

Not necessary to add them all…… but then it makes it much easier to switch back and forth and know what to expect, so maybe does make sense to add them all.
