Started working on bullet
Merge branch 'develop' into bullet
Fixed the bullet libraries.
Added the IBulletShape interface and BulletShapeMesh

BulletShapeMesh is a component used for static meshes that can be
concave and don't move.
BulletShape no longer causes a crash on dtor

The order of member deletion was wrong.
BulletShape now allows rotation on initialization
ViewMover's view is now protected instead of private
Added BulletMover

BulletMover moves a view according to the corresponding rigid body.
Hacked in a static BulletMover into BulletPhysics
Made BulletMover smaller

BulletMover's rigid body collision shape is smaller now.
Rotating the BulletShapes by radians on Y axis
Cleaned up main.cpp and add BulletMover and BulletPhysics
Merge
Fixed wgl glew extension problem
Bullet physics integration on Linux

Mostly just updates to cmake so it searches for all 4 bullet libraries and links the relevant 3 (or should it be 2?)

also bulletphysics.cpp had some windows style paths. Case-insensitive includes must be lovely...
Merge pull request #35 from tanderegg/develop

Fixed wgl glew extension problem
Merge pull request #36 from wrongu/develop

Bullet physics integration on Linux
Changed BulletMover to use a capsule instead of sphere
Fixed GLCubeSphere using the wrong texture index

GLCubeSphere was using the GL_TEXTUREX which indicates to GL when
binding a texture which slot to use. Instead it needs to set the slot
index.
