Handle censored track titles from Apple Music in library matching

Browse source 
Apple Music returns censored titles like "B*****t Faucet" for
"Bullshit Faucet". The string similarity function now detects
asterisk patterns and matches by comparing non-censored words
exactly and censored words by prefix/suffix characters.

Only fires when * is present in one string — zero impact on
normal comparisons. Prevents daily re-downloads of explicit
tracks that exist in the library under their uncensored names.
