Highly Complete: Fix crash on paths containing URL escapes

Browse source 
In the event of local paths containing not just UTF-8 characters,
but also un-decoded URL percent sequences, which will end up double
encoded in the player, code which reverses percent encoding should
later re-apply it.

Apparently, this whole time, since the last code overhaul, the
URL encoding was being stripped, then the file opener was converting
these paths back into URLs without re-encoding, which didn't break
until someone played an album in a folder containing a partially
decoded UTF-8 sequence. Thanks, Zophar's Domain, and whoever ripped
the Golden Sun GSF set for finding this bug!
