Docset archives for OpenGL ES 1.1, ES 2, ES 3 and EGL 1.4

These are the docsets I have been using on a day to day basis for OpenGL ES and EGL development. The same are hosted as feeds at https://github.com/chinmaygarde/OpenGLESDashDocset

I am not entirely certain if I have used the `major_versioned` key correctly in the JSON file (especially for the non ES 1.1 feeds). Suggestions for fixes welcome.

Thanks for Dash!
