Make drupal_cms_olivero the default front-end theme

I'd like @mherchel to look at this. The end result looks identical to what's in HEAD, but it's using drupal_cms_olivero, which inherits all settings from Olivero and includes copies of its blocks (except for the Search ones).

Just pushed a commit with regions and a disclaimer. Regions are necessary.

Should be GTG!
