Add line, plane, ray and segments, split math unit test

Browse Source 
Added some basic geometric primitives such as planes, rays, segments
and lines (plus some extra functions like xProject, xBarycentric, Lerpf),
as well as some intersection tests between them.

Additionally, I split massive math test into smaller ones and tweaked
unit test library (testing no longer stops after first failure).
