[Tagging] wetap specific tags

The automatic "source=wetap" is not correct. If you check with the app that
a fountain is working, and that sets source=wetap, this is factually wrong.
Also the concept of source=whateverapp is not correct, when whateeverapp is
a tool to enter data which come from the user of the app. So in most cases,
where there is no pre-existent source tag, you could think of manually
inserting a source=survey tag.
In the specific case of drinking fountains, this seems to be the attempt to
insert something that indicates that on the date of the change the fountain
was working, but that needs to be a different tag.
And this raises the obvious question: Do we have any way of tagging "tag
value verified by survey today" ? This would be helpful in many situations.
I am thinking about the repeated discussions about explicily tagging
default values in order to underline that the value has been checked.
