Description
Add Loyality Prefix on Pet-Eggs.
Like the same way named Pet Eggs are shown with the beloved prefix.
Also add a flag to the Market-API.

If you have several Eggs in the Storage is hard to find out, wich of them are not loayal yet and wich are.
This would also give the possibility to vend loyal Pets.
