Updated BlackBerry references to make note of the change from FREEGLUT_GLES2/1 to FREEGLUT_GLES.

Browse Source 
Updated BlackBerry toolchain to support building with Dinkum and to support OS 10.3 and GCC 4.8.2
Updated BlackBerry fg_window_blackberry so that window usages aren't hardcoded based on compile information, since it is now controlled by glutInitContextVersion.
EGL window setup now supports EGL 1.5, Renderable type for ES3, and using the minor version from glutInitContextVersion to have more exact control over which version of OpenGL ES is used (requires EGL 1.5)

To change which version of OpenGL to use, call glutInitContextVersion(1, 0) for OpenGL ES 1.x, glutInitContextVersion(2, 0) for OpenGL ES 2.0, or glutInitContextVersion(3, 0) for OpenGL ES 3.0.
