Pool level range + reload command

With this release, the /reloadwondertrade has been added to reload the config after edits without having to restart the server!

Additionally, the admin commands (reload/regenerate) now give feedback to at least tell you when they have finished running.

Some new configuration options have been added that allow you to set a level range for the pokemon within the wondertrade pool. Those will get applied whenever the pool is regenerated (so if you make changes to these config settings, they will NOT immediately update the pool).

On top of that, I took the level range further with an additional config setting adjustNewPokemonToLevelRange - a config setting allowing you to tell wondertrade if a pokemon is outside of your pool level range, it will get automatically adjusted when the player trades it into the pool.

Example: You have a poolMinLevel = 5 and a poolMaxLevel = 15, if a player trades a level 20 Pokémon, it gets inserted into the pool with level 15 instead.

Lastly, a bug was fixed where wondertrade would accidentally add pokemon to the pool that got blacklisted by you.

Do let me know if you discover any issues with this release!
