Move roll labels into a handlebars helper

[orffen]

Pass data from the item/actor into the handlebars helper function to return a formatted roll label.

For example:

Handlebars.registerHelper('localizeRollLabel', function(data) {
  return `${game.i18n.localize('BASICFANTASYRPG.Roll')}: ${game.i18n.localize('TYPES.Item.' + item.type)} - ${item.name}`;
});
