Added lol::phys::Simulation, lol::phys::EasyPhysics for easy physic uses.
Added PhysicsObject, wich hold EasyMesh & EasyPhysics components so it is easy to use. Easy seems to be the consensus.
BtPhysTest now works with new physics classes.

Known problem for this commit:
Physics is not properly setup.
There might be memory leaks, I don't think I've parsed all new/delete.
A LOT of primitives are not taken into account.

GLSL grammar and some personal attempts at writing an HLSL grammar.

Added BtPhystest for Bullet Physics test project.

software is installed.

tarball.

make sure each .vcxproj file is with its corresponding source code.

functions; also remove a lot of idiotic "using namespace std" from the
codebase.

"half" class. The build is now 3% faster.

personal taste.

more unit tests for the quaternion to 3×3 matrix conversion.

mathematical writing, and add static constructors to create quaternions
from a rotation.
