Configurable spacing for site title page headers

There should be a theme setting to control the removal of spaces in the site title on the page headers. This cannot be reliably done with CSS, so the theme removes the spaces turning 'Site Title' into 'SiteTitle' placing every other word in a span for an alternate color.

Add an option to use normal spacing in the site titles. Default behavior should be the current behavior. If spacing is turned on, the alternate color span should not be added.
