    eslint: tell eslint not to ignore files in node_modules/*
    
    eslint "helpfully" ignores all files in node_modules/* and
    bower_components/* by default (even if --no-ignore is passed).
    
    This is fine for command line usage, but in Builder, assume
    that if the user opens a file, they really want diagnostics
    for that file, regardless of its location.
