feat: skip null elements

[nxmndr]

Hello there !

Here is my modest contribution regarding this feature request. Basically this allows more lax CSS selector rules in order to target more elements, in particular the forum current language, eg. with html[lang="nl"] .some.selector.

Here are some sources :

• Regarding CSS selector rules : https://stackoverflow.com/a/6732899. Following links on this page appears to show many chars are allowed in CSS. I only disabled line returns.
• Regarding skipping empty elements (by driver.js author himself) : If element is invisible/hidden, it should be skipped kamranahmedse/driver.js#25 (comment). Unfortunately, it appears a timeout is necessary

I would need this for a multi-lingual forum. I'd gladly take any criticism.

Best regards
