VIM: Use Arrow keys to navigate in normal mode

[jtestard]

Hi Jarrod!

Just wanted to say that I enjoy these dotfiles quite a bit, they are definitely improving my CLI experience!

I was just put off by one thing: in Vim in normal mode, the arrow keys are mapped by default to resize windows, where the regular vim default is to use them to navigate.

I just added some overrides in my custom config extensions, but I would recommend to provide an easy way for user to get access to the navigation keys upon install, maybe in the readme?

Best,
