Flac > Flac conversion, tiny update

DON'T USE THIS RELEASE!!! It's broken!!! Use 3.3.27 or current stable branch commit, which has this corrected!! Sorry about that.

Just because, well, sometimes in rare cases you might want to rerip flac files you got from some random place to a new set of flac files.

For example, if you get some old flacs, and just want to make sure they are actually up to date and with the quality level you want, you just run:

acxi -i flac -o flac -s [source] -d [destination] -q 8

and away you go, new flacs. Note, I came across a case where a very old flac file would not convert to a lossy format because there was something wrong with the flac formatting, the codec was too old that had been used to convert it, or something, in the end, with that one, I just used audacity, open file, export to itself as flac, then it all worked, but I thought, well, why not? Sometimes you have flacs you have little to no idea about how they were made, and maybe you prefer always having quality 8, as in the above example, and don't want to spend any time researching the old flac files.

As changes go, this may be the smallest one ever, I think I only had to add something like 4 to 8 characters in acxi, but might as well call it the current acxi re releases.
