Display egg groups

[Denmark14]

Add a component, under forms, but above learnsets, that displays the egg group of the currently selected Pokemon. You can add the sprite of an egg here to clearly indicate it's purpose.

• Requires util update
• Requires egg group names
• Ticket scope should be expanded to alert devs as to invalid egg moves (ie. can learn a move via egg that none of it's partners can learn, making it irrelevant)

egg group names are still not implemented yet - we need to update game data
