Changes to match latest Schema:GettingStarted

Field changes per Schema:GettingStarted rev 4964628:
replace protection with isEditable (based on presence of [Edit] tab),
drop returnToTitle, editCount, rename some fields.
Rename task funnel.

With this Community portal no longer logs clicks, but leave its Schema
module present to avoid transient breakage.
