[Feature request] Add Brave as a search engine option

[fromtheeast710]

I have been using Brave search as my default search engine for quite a while so I would like to have it in one of the search engines available by default. Adding it manually means IceWeasel won't display it's icon properly.

I hope you consider this as Brave is an excellent alternative to Google search.

Thank you.

@Jagazz Yes, I am aware of this. What I meant is that IceRaven should ship with Brave.
