Build fails due to GLM/GLX experimental flags missing

[DolphinDream]

Compilation failed due to using glm/gtx/transform without proper enabling of the glm experimental extensions.

To fix this I added this macro to the cookbookgl.h file (which seems to be included by all other main files)

#define GLM_ENABLE_EXPERIMENTAL

My system configuration:
OS: Ubuntu 14.04 64 bit
GLM: v0.9.9.0
GLFW3: v3.2.1

Thanks for the report! It looks like this was just added in GLM 0.9.9:

I think that we should remove all use of GTX extensions. There's no need to use them. I think I just found them more convenient.

As of 37903a2, I've removed all use of GTX extensions.
