In-browser snippet copying

[ramiabraham]

Adds copy functionality using execCommand(‘copy’) to directly copy the code snippet to the clipboard.

• Will fallback to cpt.openSnippetCopy() on failure.
• Uses cpt.browserCopyStyles() to set styles because I couldn’t immediately locate an effective means to manipulate styles via the scss/css alone.
• wp.a11y.speak is commented out in two cases in frontend.js, as the eslintrc config returns an undef error on wp. A custom global/environment handler for wp - or a line-level eslint rule is required (or suppression of the error itself).
• Needs a grunt build ( I opted for the courtesy of me not compiling in the PR).

Hey @ramiabraham, tried testing this, but it never copies to the clipboard. Which browser are you using where this works?

[ramiabraham]

@jtsternberg did you compile grunt first?

[jtsternberg]

Yah. I think I got it now. Thanks
