Trainer info in modal

[vinnymac]

Much like the one in the mobile app, it would be nice to display the badge and trainer info. We would request this information each time before we display the modal. Other work such as #112 might be a little more risky as it requires keeping the XP bar up to date, which users will always expect to be up to date. The modal would be a lot less error prone, and fun to work on. It would appear when you click on the trainers name.
