Help with testing vim-mode-experimental

The branch vim-mode-experimental needs testers and contributors.

Follow the build guides provided in the README.md and git checkout vim-mode-experimental.

Keybindings aren't configurable yet, but that's going to change. Keybindings are the same ones vimium has, except for closing tabs being bound to xx instead of x, to prevent accidental closing. You can look into config.go for all features and change hardcoded bindings to your liking.

The find feature doesn't work fully, because it doesn't scroll. The focus first input box feature is a stub currently, but f (link hinting) also works for selecting input boxes, so this shouldn't be a big issue.

You can use vc (visual mode > caret mode) to try caret mode navigation, where you click with Enter

Tests for the different features are missing, so this is certainly one way in which you could help, by writing tests.

The vim-mode-experimental branch breaks a few tests, and I know the cause for most of them. Will fix that hopefully soon.

If you run into bugs with this branch, please report them.

Feedback welcome!
