NPC/Dungeon/Lore Navigation Templates

Found a work around. Using set operations, we can perform a set difference to "subtract" <removed content> from <all results>.

Using this, ([[User:Dfoplayer/TestFilterRemovedContent]]) the code in your navigational table should look like <code>{ {User:Dfoplayer/TestFilterRemovedContent|catePara=Time Gate Dungeons|sortPara=Has dungeon entrance level requirement}}</code>

I think this is a good start. If you like it, I'll a few more days to make it scalable to work with other templates. Navigation requires a single line list while the skills should be in a table format.
