Headings: Change H4 subtitle to capital case or lowercase

Capital case:

Lowercase:

The H4 subtitles use a class that converts your headings to always be uppercase for consistency. This code change allows you to override that and make it capital case or lowercase. 

Code for capital case:

/* -- code to convert h4 headings to capital case -- */
h4.home__subtitle {text-transform: capitalize !important;}
/* - end - */

Code for lowercase:

/* -- code to convert h4 headings to capital case -- */
h4.home__subtitle {text-transform: lowercase !important;}
/* - end - */
