Fix module path affecting audio output [CORRECTIVE]
- always use UADE: as the directory seen by Amiga side
- initialize path/dir/file array outside score to avoid having to parse/split the path during score init
- add vblank wait after ext_load to fix also TFMX etc. which parse the file name for ext file loading
fixes also very long path names (> 127 chars) breaking at least MusicLineEditor
