Title: Split -mask detect into -mask and -mask-repeat

CSS Mask detect was returning negative despite its support in Chrome/Safari. It was testing ```maskRepeat``` prop instead of just ```mask``` so I corrected the original and added a new ```maskrepeat``` test.

```maskrepeat``` metadata is updated too. Removed both caniuse and the blurb about FF ```mask``` feature with the same name
