- Fix glGetStringi's return type to String

- Fix ExtensionAvailabilityCache:

    GL3's glGetStringi for GL_EXTENSIONS

    Ensure to add GL_VERSION_2_0 in case version >= 3.0

    Ensure to not exceed version 3.0 for non GL3.1 context.

    In case of GL 3.1, do not include GL_VERSIONS below 3.0,
    since this is a forward compatible context.

- Add Prologue to glGetString, where the ExtensionCache is being
  used for GL_EXTENSIONS - if already initialized.
  This feature adds backward compatibility for GL3 context on GL_EXTENSION.

General:

Add GLPipelineFactory, a convenient pipeline factory for Debug/Trace and custom ones ..

Change 'void setGL(GL)' to 'GL setGL(GL)', and let it return the successful set GL,
or null.
