Preliminary support for neovim

A simple change to support neovim. Fixes spf13#774.

Move nvimrc file inside .nvim directory

Only install neovim support if neovim is being used

Use program_exists function instead of vimscript

Made a hasty mistake and added vimscript to a bash script :X

Neovim not existing no longer stops script

Also correct `endif` to `fi`.

Refactor program_exists naming

Changed `program_exists` to `program_must_exist`, which throws an error which halts the script if the program is not found, and refactored `nvim_exists` to be the more general `program_exists`, which does not throw an error if the program is not found.

Refactor program_exists and program_must_exist

`program_must_exist` uses `program_exists` now, instead of repeating code. Changed `type` to `command -v` in `program_exists` to be more POSIX compliant. Refactored status code conditional in `program_exists` to remove double negatives. Thanks to @mkwmms for the suggestions.
