Support for other keyboard layouts.

**Topic**
Configure lazygit to be able to use other keyboard layouts efficiently.

**Your thoughts**
I use colemak dh. With vim, it's easy to configure hjkl keys to work on it. My problem is that I run lazygit inside vim and that ends up screwing up my workflow since I now have to use the arrow keys to move around.

Is there a way to set hlkl keys to work with other layouts. Have this issue come up for other people?
