I think the NERDTree window should not resize between multiple toggles.  Makes it difficult to read the longer file names.

improv: set shell to ZSH in interactive mode

In interactive mode, ZSH will read `~/.zshrc`. Else, it will first stick to
`/etc/zshenv`, then `/etc/zprofile` and last to `.zshrc`. Without this, running
shell command from within Vim may result in `command not found`.

improv: set shell to ZSH in interactive mode
Check to see if zsh is even used

Last commit (9569441) was breaking my vim.  Whenever I try to start vim it just would segfault. 

$ vim
[1]+ Stopped vim

If I take out this change by removing the "\ -i" vim starts up fine.

I don't use zsh so not sure if that has anything to do with it.  My pull request checks to see if the user is even using zsh by checking the presence of a .zshrc file.
