Switch to neovim

Vim was giving me static: every time I opened a file, I had to Ctrl-C
before text would appear.  Then when I tried to save, it would warn me
"file already exists".  Then when I tried to open another file in a tab
or split, it just wouldn't work.

Installing the neovim python package is currently necessary to make
`nvim +PlugInstall` work right: junegunn/vim-plug#104
