Add 'user-select' to vendor mixins

[mehcode]

http://caniuse.com/#feat=user-select-none

---

This should probably generate as follows:

.unselectable {
    -webkit-touch-callout: none;
    -webkit-user-select: none;
    -khtml-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
}

I'm not sure how you'd like adjust the vendor stuff to do the above.

Hi, thanks for the report (and the request).

Will you please add some unit tests for this feature ?

Added. Also updated to generate what I mentioned in the opening.

Hi, thanks for the tests. I would prefer to keep using the ks-vendors() internal mixins, since the used vendors prefixes in the output will be dependent of which support you define with kouto swiss. I will correct that with the merge.

Has been implemented & published in version 0.11.7.

Thanks again.

@leny If you use your ks-vendors mixin it doesn't generate it 100% correctly (in my opinion).

It'd be missing the -webkit-touch-callout: value line.

I'm a bit confused about including it, since it's really specific and not totally related to the user-select property.

In the current case, I think the best is to define your own mixin extending the one from kouto-swiss, like this :

user-select( value )
        -webkit-touch-callout: value
        ks-vendor( "user-select", arguments, feature: "user-select-none" )
