Amarok export scripts

Preamble

Amarok scripts

I use those scripts to extract tracks from Amarok DB. Ever since Amarok 2.x launch extracting number of songs to external media became a hassle, so I had to "compensate". To successfully use USB stick in a vehicle entertainment system it's best to store all mp3's in a single directory. However track names may collide, thus we're renaming them to their md5 checksums to avoid collisions.

Typical usecase::

  ## export everything with rating higher than 3.5 stars:
  $ python export_rated.py --rating=7 /media/MyDevice
  ## add some random songs from my collection for a good measure:
  $ python copy_random.py -R5 -s .mp3 -n 50 /mnt/music/MyCollection /media/MyDevice

As a result - /media/MyDevice will contain a number of .mp3's within root directory of the form::

   aaeca6fdeecd1425a0aadeb1ad81b5a0.mp3

Now vehicle entertainment system can quickly scan the device and have no issues with file names.
