filter suggestion: base quality

[GormanGhaste]

Under the pet properties category, I'd love to see base quality added (uncommon, rare, etc). It's already in the Warcraft Pets database, and it would be very helpful for when I get a rare stone and want to find a duplicate pet to use it.

We're discussing adding this filter, however we'd like to first ensure all pets have the correct base quality. It will take some time to manually review all pets and then add the filter.
