Add ability to have a default search engine.

Use the boolean "default": true or "default": false to have only 1 engine as the default.

For the default search engine, a default keybind is now present ALT+x

So if Brave Search is set as the default, you can simply use ALT+x on a selected text to search with it.

Full Changelog: https://github.com/dpi0/srch-firefox/compare/v2.2.1...v3.0.0

[!CAUTION]
v3.0.0 has breaking changes in which the addon has moved to a chorded keybind system.

Your old ALT+x for Google, or Alt+y for YouTube binds won't work now.

Use the chorded LEADER --> g for Google and LEADER --> y for YouTube (default LEADER=ALT+c) from now on.

1. You can now fully customize each search engine via the options page.
2. Use chorded leader based keybinds to use each engine.
