-New: Refactored code base to follow directory and file structuring of other Give add-ons.
-New: Revamped the UI for adding tribute types within the global settings screen.
-Fix: Tribute notification email sent to admin when a new donation added using the Manual Donations add-on.
-Fix: Resolved incorrect output of the {tribute_info} email tag.
-Fix: Removed the first "delete" option from the UI when multi-recipients are enabled for eCard. The first notification email is required therefore the option to remove should not be available to donors.
