For feeds that provide a list of categories for each
item, the application should have the ability to
automatically attache FoFR tags for the items in those
feeds.
The xml elements that contain tag/category information
are (in decending preference order):
<category>
<dc><subject>
<media><category>
Each tag can have 0 or more aliases associated with it.
An alias is an alternate name for the tag to allow
differing input values. ("PHP", "PhP", "Php", "my php
stuff")
A tag can be converted to an alias. The tag the alias
will point to must already exist. If any items are
already linked to the tag, they are migrated to the new
the tag the alias points to.
The user should have the ability to enable/disable auto
tagging at the global and per-feed level.
