Success result wording

[jeremiahsmall]

If you use directory instead of file paths, the success message is worded oddly.

>> 3 files lint free.

See https://github.com/SaschaGalley/grunt-phpcs/blob/master/tasks/phpcs.js#L69

The simplest fix would be to change the word file to path so instead the above message would read

>> 3 paths lint free.

While we're talking about the wording, there's also grunt-phplint, so I'm not sure talking about "lint free" in the result message of grunt-phpcs is the best choice. In the vernacular of PHPCS, they are called "sniff violations." If we use "sniff" it could be reworded like this

>> 3 paths contain no sniff violations.

If either or both of these wordings are supported, I'm happy to submit a PR.
