Support running the ESLint server in the WSL under Windows.

This is the error I get in the output pane of Vscode. There is no log in the developer tools console.

[Info  - 9:16:38 PM] ESLint server is running.
(node:11580) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): SyntaxError: Unexpected token .

I can lint the file fine if I start eslint in the console (Bash for Windows).

I do use Vscode in Windows 10, and eslint (and nodejs) is installed inside Bash for Windows (Linux subsystem). My Windows build is 15063.296. Node.js version is v8.1.0, eslint is v3.19.0. So I start the Windows version of Vscode but I point to eslint inside Linux with "eslint.nodePath".

Found a more reliable way to use WSL-installed node & eslint, using the wsl wrapper command that is part of WSL.

1. Create a batch file with the following content and save it as node.bat:

   @echo off
   wsl node %*
   

2. Make another with node replaced by eslint (Can repeat this for whatever other commands you need to be made available).
3. Set eslint.nodePath to C:\\path\\to\\batch\\file\\node.bat (note the double backslashes)
4. Restart Code if needed.

Will close the issue since there is nothing to do in the ESLint extension 😃
