Use a better ruleset.

Note:
* As the WordPress ruleset includes all WP sniffs, specific sniffs which were not in the VIP ruleset don't need to be included separately anymore.
* As the WordPress ruleset includes the Docs ruleset, no need to include it separately. The related rule exclusions have been moved up to the main ruleset inclusion block (except for the scalar type hint one as that is no longer needed).
* The GlobalVariables sniff was intended to be added, but commented out for bugs. As it will now be automatically included as the ruleset has changed, it will need to be explicitely excluded. The exclusion can be removed once WPCS 0.11.0 has been released which fixes all known bugs in that sniff.
