Added customized styles for the homepage hero pattern.
Note that there are several necessary custom classes applied to the pattern that should not be removed when editing.
Added support for a new button style and updated existing button styles.
Added new functions partial to begin adding custom categories. This is the initial attempt to do custom categories; we can dial this in later when we have more blocks.
