Added support for Reading time plugin

I added support for readingtime Grav plugin for cards and boxed post layouts. Also has been included in item's template. Then you could customize the output string and words-per-minute in plugin configuration.

Breadcrumbs updated

Style of breadcrumbs is now following Bootstrap 4 pattern. You don't need to disable plugin css, but is highly recommendable. Keep light your site!
