Changes enable gathering track numbers from quicktime (m4a) files.

I consider this a "work-around" because I don't see a need to automatically require a quicktime file to be searched for id3v2 tags. The getID3 library seems to do a pretty good job of determining the correct means for gathering the data from the varying types of multimedia files from itheir signatures.   I'm not sure that "getid3_tag_order" needs to  even be in the config file to confuse the user.  I know it sure does confuse me,   

Also, there are a number of people with very large collections that take hours to process: Removing the redundancy, may reduce the catalog management time maybe by half.  Expecially with a large collection of 1+ gb mp4's.  

Of course if there is a real need for the duplicity, then "Never Mind...."
