Feature Request: this.entity_attribute[attributeName] replacement

[dave-gray101]

I'd like to generate cards with more fields than just the entity ID substituted in. I created this quick PR to fill in arbitrary attributes instead, such as friendly_name. It might be better to support a full template execution, but this seems like a good middle ground, potentially?

Please let me know if you have any suggestions on a better way to do this.

I'd really love to have this feature, so I can make url navigations to edit a scene by its id attribute

This PR works well I can confirm. Can this be merged?

Push, i tried over an hour, just expecting that this.entity_id is not just magicly hardcoded but would work similar for other attributes untill i found the section in the sourcecode :(
