Backlinks not generated with {{image}} links to internal wiki pages

[BrianKoontz]

From the wikka-community m/l:

When I add an {{image}} to PageA and I use the link parameter to link to
PageB, PageB still has no backlinks (at 'PageB/backlinks'). PageB is
also not removed from {{OrphanedPages}}.

This behavior is due to linktracking being disabled by default in the Action() call. This is quite possibly a security fix to prevent XSS attacks. However, I do see value in allowing users to create {{image}} links that point to internal pages and track backlinks correctly.

(In [1880]) Permit the specification of forceLinkTracking in action calls that will preserve linktracking such as with {{image}} links that point to internal wiki pages. By default, forceLinkTracking remains disabled for all action calls. Refs #1126.
