[bp/r56057][ENH] trackers: Add a new option to Category fields to allow items to be recategorised when being indexed. This will allow tracker items to appear in perspectives for instance following the parent tracker categories being changed or following an upgrade.  N.B. The change in indexing introduced in trunk in r56096 has not been backported here to maintain current (stable) behaviour, but the default comma-separated indexing has been added instead (Thanks marclaporte)
