Exchange supercrabtree/k for exa

exa is more versatile and way faster than k. I rarely used the git
integration of k (which is, admittedly, better), as well as the colored
variables. So exa should work well enough for my purposes, especially
since I make more use of vifm when cd-ing through a lot of directories.
