New features

Preview widget for ISF shaders in the library
ISF multipass support.. a few ISF files still don't work but we are reaching feature completeness.
JS improvements: it is now possible to access to musical quantization data and a lot of other features from JS scripts.
Language specific syntax coloring in code editors
Library: Faust (.dsp) and JS scripts (.qml / .js) found in the library will now be added as children of the relevant processes in the process library so that they can be drag'n'dropped easily.
