Description of the changes

This PR introduces new properties in the template context when binding:

• $index is added to the context of each item being looped with data-for. This is useful when a developer needs to know the index of an item being rendered
• $parent is added to the context of a template when rendered inside of another template. This is useful when the developer needs to use context from a parent template
• when looping, all context is preserved. Before only the item being looped was available

This PR also fixes an issue where person-card image was not passed as context to a template.
