Plugin match-braces does not work with a custom prefix from custom-class plugin

[mmena1]

Information:

• Prism version: latest from the download page
• Plugins: match-braces, custom-class
• Environment: Browser

Description
When using the plugin match-braces alongside custom-class plugin it works fine, unless you declare a custom prefix.

e.g.

Prism.plugins.customClass.prefix('pr-');

Most likely it's because this line is using the wrong selectors.

So, instead of:

var punctuation = Array.prototype.slice.call(code.querySelectorAll('span.token.punctuation'));

It should be something like:

var punctuation = Array.prototype.slice.call(code.querySelectorAll(`span.${prefix}token.${prefix}punctuation`));

I'm not sure how to get the prefix though, but I believe it's stored somewhere.
