* add support to set REACT_EDITOR to none

* change README message

* change condition to avoid problems with editor being null

* move condition to avoid extra code

Adds support for the error overlay to detect and open the file with the error in MacVim.

Relates to #2636.

* File headers BSD+Patents -> MIT

* BSD+Patents -> MIT

* Auto-detect running editor on Linux for error overlay

Basic support of auto detecting running editor for #2636.
Tested on Ubuntu 16.04.
It detects few editors. JetBrains products should start by
wrapper like /usr/local/bin/webstorm. Otherwise it takes a
lot of time to open editor.

* Comments fixed.

* List all processes owned by you

* Comment rewording

* rerun prettier for all files

* pin prettier to 1.6.1

Autodetect PyCharm (Pro and CE), WebStorm, PhpStorm, IntelliJ IDEA, RubyMine, CLion, and AppCode

Added IntelliJ IDEA, RubyMine, CLion, and AppCode to list of IDEs. It has the same signature as WebStorm and PhpStorm `<editor> <projectPath> --line <number> <filePath>` so it can reuse the logic from those.

Removed older integrations of AppCode, IntelliJ IDEA

This allows you to set REACT_EDITOR to 'vim --remote', so the file can
be opened in an already running vim process. When using vim without
remote, it works in the same way as before.

When launching vim without --remote, the order of the line and path
arguments doesn't matter. However, when using --remote the line argument
has to precede the path. This happens to be the same as joe and emacs
uses, so the vim cases were just moved there.

I haven't tested this with mvim, but the documentation says the same as
the vim documentation, so I assume it works the same.

* docs: added REACT_EDITOR to `Advanced Configuration` section

* Update README.md

* Update launchEditor.js

* Auto-detect running editor on Windows for error overlay

* Ignore process output if powershell call fails

* Support Notepad++

Both editors have the same signature `<editor> <projectPath> --line <number> <filePath>` to open file from the command line.
It seems to work even if `<projectPath>` is omitted (commit 02f88ba1).

Tested on `Win10`+`PhpStorm2016` and `macOS 10.12`+`PhpStorm2017`.
