Custom Pickup Condition Config

Both Entities and Blocks can have a custom pickup condition when
Game Stages is installed.

Format:
modid:blockname;meta(condition)
or for entities:
modid:entityname(condition)

Examples:

minecraft:mob_spawner(spawner)
This let's the player pick up a spawner when it has unlocked "spawner".

minecraft:log;0(oak_upright) This let's the player pick up any upwards facing oak logs, when it has unlocked "oak_upright".
