Support passing file names in as arguments

[feross]

Run standard to recursively check a whole project.
Run standard < index.js to check an individual file.

Need to support: standard index.js or standard index.js test.js lib/a.js to check a list of files. Shouldn't be hard to add.

looking for standard lib, where lib is a folder as well. might be useful to use https://www.npmjs.com/package/fs-readdir-recursive for that

This is implemented now! Released as 2.4.0.

@jonathanong It expects glob patterns, so standard lib/**/*.js. That work for you?

Also, listing out files one at a time works too: standard index.js test.js bin/cmd.js
