- Added the proper ability for seeds to be custom skinned player heads and just more fluid skinned head intractability overall.
- Added a protection against planting seeds in worlds with "_" in the official backend name (eg: the nether's worldname and end's worldname). This isn't a preference but a necessity because it breaks some backend stuff. It was a very silly decision I made in the beginning of the plugin that has held true through the whole development. I could just fix it now, but that would require every server using the plugin to wipe all crops and that just seems unfair so my ghetto fix is no longer allowing the placement of seeds in world names with "_".
