ESLint causes build on windows to fail with default git settings

[rmtmckenzie]

Because ESLINT is set to need linefeeds set to LF, by default on windows building this will fail.

There's a few possible workarounds - the easiest being setting global git config core.autocrlf to force linefeeds to LF. However, this can break other programs' builds. A local git config can also be used but that doesn't help if using NPM to pull this repo.

I'm going to do a pull request for adding a .gitattributes file which forces line feeds to LF regardless of the git config for *.js files in the repo.

All you need to do is edit the .eslintrc file. Change "linebreak-style": [2, "unix"], to "linebreak-style": [2, "windows"], when you are on Windows.
