Neovim compatibility

[kiryl]

Neovim changed behavior of "!" -- it doesn't connect it's stdin to anything so interactive commands would fail. See neovim/neovim#1496.

One way to get it work would be spawning :terminal for interactive commands.

I have been trying to get this to work with terminal for the interactive commands. As far as I can tell the asynchronous nature of the neovim terminal means the taskwarrior#list() or taskwarrior#refresh() commands run either in the terminal buffer or before the interaction has completed.

I am not sure how to easily make this work and am looking for suggestions.
