Google as optional by default

[Terrance]

Description

I don't use Google search, but uBlacklist is enabled by default for Google and the corresponding permissions (an unfortunate number of regional domains) are required for installation. Could the extension default to no search engines active, with these permissions made optional?

This would probably need to come with some kind of post-install prompt to select your search engines, as there'll be no functionality until one is enabled.

I'm aware from past issues that you want to avoid browsers requiring user confirmation to update when new permissions are added, but I'd expect moving a permission from required to optional to not require this? Looks like the Google domains are coming from content script matches though, so I'm not immediately sure how this works with optional permissions.
