filter-blur: Multiple changes, see description
* Added a 'Bilateral' de-noising blur, currently very resource hungry. It also has two extra sliders called 'Smoothing' and 'Sharpness', the former controls how smooth the output is * Updated effect loading to be global instead of per instance. * Changed default blur size to 5px. * Simplified render loop (see previous effect commit).
