Feature Request: Rainbow braces toggle button

[kmgallahan]

I find rainbow braces the most useful whenever I realize I'm counting braces/parens manually like a peasant to figure out the imbalance. Most of the rest of the time though the colors can be distracting.

It would be helpful to have a toggle button for the toolbar to enable/disable rainbow braces on-demand, rather than having to jump into the settings.

Thanks for the great extension!
