VocaloidLethalPhone

Add Vocaloid content for the LethalPhones mod, featuring 6 ringtones (for now):

• The World is Mine (ryo)
• M@gical Cure! Love Shot (Sawtowne)
• Miku (Anamanaguchi)
• Tetoris (柊マグネタイト)
• ぽっぴっぽ [Po Pi Po] (LamazeP)
• Mesmerizer (サツキ)

P.S.: I also plan to make skins and charms once I fix my issue with Vulkan.
