[Accessibility-ia2] Finding the most recent target of the most recent activation of an in page link

[Pete Brunet]

The originating issue is here:
https://bugzilla.mozilla.org/show_bug.cgi?id=617544

Alex's solution is here:
https://wiki.mozilla.org/Accessibility/IA2_1.3#Anchor_target

Due to the fact that this isn't a widespread issue I'd rather use a new
relation than a new method to resolve the problem.  I am proposing a new
relation, hasFlowedTo.  This is a generic name which could be suitable
in many situations.

A proposed text is:  The object which has this relation is related to a
group of additional objects, the sum of which make up a user's
experience.  The relation's target object is the object which has most
recently been presented to the user.  A concrete example is a section of
a web page that has been navigated to via an in page link such as <a
href="#foo">.
