Add the ability to Disable/Enable a selector#74

Hey
sometines we nedd to disable a selector (like our custom selectors) temporary. Now we have to remove them and re create them which is not a good workflow.
So please add the ability to disable/enable a selector in CF. it could act as a comment when we disable it and uncomment whe we enble it.
Regards

+1 This is especially useful when tinkering with other classes/conflicts/breakpoints– for whatever reason, really. Maybe with eventual option of removing/not generating unused classes, the option to include/exclude those disabled.
