Updated to new bindbc-loader version

Updating to 1.0.0

Adds some missing OpenGL ES 2.0 functions

@aubade kindly went through the official ES 2.0 reference spec and added missing OpenGL ES 2.0 functions, now they should all be present.

Updates to automatically loading different version

OpenGL ES 2.0+ removed support for a number of GL 1.x fixed-function pipeline features. This update makes the loader a bit smarter - it will auto-detect whether its loading a 1.x or 2.0+ library and will only issue a BadLibrary error if it lacks both the fixed function and shader program based pipelines.
