Title: ofxFXObject improvement

Creates the overridable `ofxFXObject::injectUniforms` method so it becomes easy to add custom uniforms without overriding `ofxFXObject::update`.

Fills backbuffer with tex0 info on first pass so it becomes easier to implement multi-pass shaders.

Update ofxBlur.h to use the new functionality. It becomes much easier to understand :)
