Implement VIM style navigation.

[mlongval]

Thank you very much for this add on. Very cool and usefull.

It is perfect in my view, the only thing that needs to be added is VIM key bindings for movement around the page: "hjkl" + gg + G etc

Thanks for the great work!

I use https://github.com/gdh1995/vimium-c for Vim navigation in Firefox. Given that Firefox's own reader view doesn't work with vimium-c it seems too much to ask that this plugin should work too.

Maybe it might be worth raising an issue with vimium-c first to see why it doesn't work with Firefox reader view.
