Sniffs for WordPress hooks

[wppunk]

Description

Add sniffs for WordPress hooks:

• do_action
• apply_filters
• do_action_ref_array
• apply_filters_ref_array
• do_action_deprecated
• apply_filters_deprecated

All these functions should be validated but the next rules:

• [ ] All hooks require PHPDoc.
• [ ] Require the @since tag
• [ ] The deprecated hooks should have the @deprecated tag
• [ ] Hooks should have the @param tag for each variable.
• [ ] Filters should have the @return tag.
• [ ] Hooks should have a short description.
• [ ] Hooks' short description should end on the stop symbol (. ! ?)
• [ ] Hooks name should be written by FQCN + method name + extra information (optional).
• [ ] Allow to add the This filter(action) is documented in /path/to/file.php if it's duplicated hook to skip all other rules.
• [ ] Add hooks you can add only in the hook method.

Also, for sniffs add the tests.
