Remove the colon " : " that is always displayed for Custom Attributes

When displaying Custom Attributes the colon " : " is displayed regardless of whether or not the label is selected to be displayed.

While I'm sure it meant something to whomever originally programmed themes (in my case, Thistle), the colon gets in the way from a graphics design perspective. In our legacy system, we used bullet points as the leader to product details.

     •  Grace Walker
     •  from the early 40s
     •  spectator pump
     •  ebony
     •  etc.

The colon limits design choices and needlessly gets in the way, either …

     •:  Grace Walker
     •:  from the early 40s
or
     :  spectator pump
     :  ebony

The colon is a hard-coded design element that is very limiting if one choses to use something other than the pedestrian method (e.g. brand: Grace Walker) of displaying Custom Attribute content.

I presume it would be a simple 'fix' to remove the forced use of this colon.
