Support for neovim

[letientai299]

There's nvim-wrapper. Recent version of neovim for Ubuntu also come with a terminal wrapper by themeself (I'm not sure if they're using nvim-wrapper directly or not).

So, I believe we could replace gvim by nvim for neovim user. How do you think?

if this could be configured to a specific binary it'd be better. as I use urxvt, so i modified the script to run urxvt -e nvim

How about define a ENV variable which take default value as what we currently have for 3 systems, user can then override that variable with whatever they want?

I'm closing this since this is nearly a duplication with #73, and also the idea that allow custom editor is mention in this comment.
