GazelleGames pet leveling info with last dropped item

Adds pet leveling info to your own GGn profile page, showing you how long it'll take for them to reach higher levels.

(Freshly-equipped new pets may not show up until they've gained at least 1 XP due to API limitations.)

--

Newly added feature includes showing the last item dropped by your equipped pets by parsing your user-log and comparing the pet name, and slot position.

Version 1.5.0+ uses the API for user log gathering.
