Add support for specifying extensions

[ericfrank]

I'd love to be able to lint .phtml files in Atom. On the command line I can use phpcs --extensions=php,phtml, but I don't see a similar option here. Thanks!

had you found a solution for this?

you can workaround this by adding following line in the ruleset of your config file phpcs.xml:

<arg name="extensions" value="php,phtml"/>
