Jim Broadus 1309c76bec tagreader: Relocate artist/album/title guessing code 
Move the code that attempts to fill missing song metadata out of the
tagreader worker. In the main process, it will be controllable using
settings and calling context.

The methods were moved into a new SongPathParser class that checks new
settings to determine if action should be taken.
