WIP: Feature: scan dirs

[rmikalkenas]

Issue: #5

Using symfony finder component I have managed to implement ability to define directories in config files in which yml/yaml files would be found for checking.

Remaining question:
currently all files inherit options defined by directory. Maybe it would be useful to exclude files from scanning if they are defined in config file? For example: if config file contains app/config: and next line app/config/services.yml, then I think we should exclude services.yml file from scanned files in app/config directory and use options defined under that concrete file.

@rmikalkenas Hi! Thanks for the PR, but I'm sorry, I'm not using this tool anymore, so I can't review this. (The reason is that the Symfony configs are now split into many small files where sorting is less useful - I keep them sorted logically instead),

But AFAIK @OndraM has been using yaml sort checker, so maybe he will find some time to review this.

@rmikalkenas Hello, maybe I will behave as asshole but I have library for yaml standards too and that library knows to find all .yaml/.yml/.yml.dist/.yaml.dist in directory but it's true it doesn't know to exclude keys from alphabetical check (yet). So, if you are interested you can check it out.
