Rewrite ns.sh

I first tried to make it into a two-level fzf menu, such that selecting a
namespace dropped you into a second fzf interface that let you select the
command you want to run. I did this because, often you want to perform multiple
actions on the same namespace, rather than jump between namespaces. But this
turned out to be unwieldy, so I went back to the single fzf with bindings for
actions, and I just cleaned up the code and tried to make everything easier to
read or use.
