Twenty Sixteen: Button blocks don't apply custom colours

[laurelfulford]

The selectors used for Twenty Sixteen's button blocks are too specific, the styles for the editor custom colours don't override them on the front-end.

Twenty Sixteen - custom colours applied on front-end after patch

[laurelfulford]

45427.patch​ adjusts the selectors used to apply background and text colours to the button block, and the selectors used to apply the custom colours. This makes sure the selected colours override the button's default colours.
