Proposal: Remove Transaction ID from message templates

Six message templates (event online and offline, contribution online and offline, membership and payment/refund) include Transaction #. I don't think this is useful information for the recipient, as it is just a long string of characters. So my proposal is to remove it, to simplify the templates and only send pertinent information to the recipient.

The only potential use I can think of would be in some edge case where perhaps you can't find a contribution for some reason and you could in that case search by transaction ID, but that seems rare and easily covered by having the exact time, amount, etc. If we did want to have something for that purpose, contribution ID would make a lot more sense, but I don't think we need either. Has anyone ever used the transaction ID from a receipt for any purpose?
