if appropriate.

do not open a console at startup.

+ Constraint hollow class.

+ weird racist test : the primitives only collide with their same type.

Phys::Simulation is now an entity.
Phys::Simulation now implements timesteps correctly.

the mathematician-friendly [w x y z].

and add a new "UseBullet" configuration flag.

Added several delete/destructor, speeds up exit & saves memory.

EasyPhysics : Added Cone primitive.

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.

library (the same that we use for the engine), and link with winmm.lib and
dxguid.lib on that platform.
