* Add ThanksPresentationModel and FlowThanksPresentationModel
* Rename notification-thanks-flyout2 to notification-header-edit-thank,
shift parameters around and add GENDER support for thanked user
* Rename notification-flow-thanks-flyout to notification-header-flow-thank
and shift parameters around; this one did already have GENDER support
for the thanked user
Depends on Idb975feaec in Echo.
