v0.4.2-alpha Adds new meta tags and more data rich HTML

[caendesilva]

Adds new config options for metadata tags. Also adds more data-rich HTML properties. Validated using schema.org and Google Rich Results Test.

Upgrade guide:

Make sure to update your config using php hyde publish:config [--force]

The new config section:

/*
|--------------------------------------------------------------------------
| Global Site Meta Tags
|--------------------------------------------------------------------------
|
| While you can add any number of meta tags in the meta.blade.php component,
| this config setting allows you to easily customize some common metadata
| tags so increase your SEO score. You can keep them to their defaults
| or you can set a value to false or null to disable it completely.
|
| Note that some tags may be overwritten on certain pages, for instance post pages.
|
| Tip: See https://www.w3schools.com/tags/att_meta_name.asp
| for a list of tags and what what they are for.
