Configure addon to only send to console panel `console.log` attempts

[keul]

I didn't find a way to wrap only console.log attempt to be sent to the console add-on, while keeping normal behavior (browser's console) for console.warn or console.error.

I think that is some situations this can be useful, at least to skip React development mode warnings.

looks like it's something that we could improve in this addon
