Moving of audio to Main repository sometimes creates a directory within a directory

[kmaclean]

Problem where there are two copies of new submission in the Main subdirectory ... one inside the other (usually Main/8kHz)

Might be a timing issue ... svn may not have time to complete the copy process before the downsample code starts running at the OS level ...

added a sleep(60) entry to Main.pm to try to address this

If this occurs again, need to check to see which one got downsampled (both or the inside directory one only ... if the latter, then it's problem with Downsample script)
