Copy non-flac files option does not check if non-flac file already exists

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run flac2all on input directory with flac and non-flac files, with copy 
option, ala "./flac2all.py vorbis Library -c -v ... -o Portable".
2. Repeat step 1.

What is the expected output? What do you see instead?
flac2all will skip copying/converting files that have already been converted 
from flac, but will re-copy and overwrite originally non-flac files. On large 
input folders this wastes significant time and I/O.

What version of the product are you using? On what operating system?
v3.71 on Linux.

Please provide any additional information below.
An option flag to change this behaviour is fine if people want it that way. Or 
maybe a file hash check to detect differences would be preferable?

Confirmed. Not much else to say really. Will let you know when I have a version 
you can test.

Ok, revision 80 should have proper support for this issue. Please check it out 
and let me know if you see any bugs/problems. 

Thanks, ZV.
