Version 4.41.0

The music packages have been split into a separate download, since they make up a large amount of the download size.

• The BTS style has been removed, due to it being rather substandard and not really possible to function in the puzzlemaker.
• New Item: Antline Corner item, which allows for manually placing antlines anywhere. Place two down with a straight line between them, then link with antlines. A contiguous section is treated as one item, which acts like an OR gate.
• New Item: Half Obs Room, a half-voxel wide Observation Room. The P1 room has switched to be a full voxel like other styles.
• P1 style light strips now are a rectangular lamp like other styles, with the square hole split into a new item.
• Add brand new versions of Old Aperture SP spheres, and 50s+60s entry corridors all by @Critfish.
• Old Aperture and P1 Gel Droppers now have new custom models.
• P1 and Old Aperture exit signs will now reposition themselves like other styles.
• Vactubes now have P1 and Old Aperture styles.
• Remake some P1 entry corridors.
• Add new option for making fizzlers force black tiles on adjacent tiles to discourage portal bumping.
• Selector windows now save/load their position and group expand/contract state.
• The pipes in Enrichment Spheres now can appear in several random positions.
