[Request] Allow browser specific rules

[tcptomato]

Unfortunately not all functionality is implemented on all browsers ( script:contains would be a perfect example). I think it would make sense to allow for browser specific rules, like

example.com##script:contains(ads)$firefox
example.com$inline-script,chrome

I had a similar idea here: #1178 (comment)
Yours seems better though.

@gorhill What would be your recommendation to use in a filter list to block things efficiently on both browsers? Using a coarse filter (for chrome) on firefox ( where you can use a finer one) is not the most efficient thing in the world.

Blocking all inline scripts is easy using dynamic filtering pane. The wholesale blocking of inline scripting by default should be left to the user given how this can cripple a site.

I'm sorry, I think I should have explained the use case better. It's to remove some annoying anti-adblocker scripts on specific sites, not something that should be done by default. The option here would be not use the site at all, or use it in a crippled fashion. (if using the inline-script option). Unfortunately this filter could be replaced with a better one on firefox, but at the moment it can't be done in an automatic fashion using a single list for both browsers.

And I don't want to impose myself, but could you please give me a feedback on my pull request.
