Potential Fix for this issue

This is a potential fix for the issue.  The issue was being caused by the class btn-group on the hibachiActionCallerDropdown's output. This was doubling up on some of the listing pages create buttons that had dropdowns.  However just removing the extra btn-group would then break other places that were utilizing hibachiActionCallerDropdown.  I added an attribute that could be passed into hibachiActionCallerDropdown and depending the boolean value hibachiActionCallerDropdown would then output html with/without the btn-group class.  I only applied this to product's listing view so that you could see it working.  If you give me the green light with this fix, I'll implement it throughout the rest of the core.
