Node & Color Picker Patches

Hi

I’ve added a couple of patches to the tracker just to practise coding.

I’d appreciate some feedback here if you think they would be useful. Please don’t spam the tracker.

Mute node wires - This patch adds the ability to mute individual wires in the node editor.

Expanded Color Picker - This a patch to expose the RGB, HSV/L and HEX values permanently without the need for switching.
