Properly handle "true song name" even with folders/categories and file formats (paving way for folder-categorized music lists set up by servers)

Prevent BG's from falling back on default BG path (this isn't really user-convenient and causes more trouble than its worth, e.g. stands appearing on BG's that dont' want stands to appear)
Implement Case Cafe's method of categorization for (a) and (b) emotes
