* Add encoding using Xiph.org 'flac' program.
This adds a FlacEncodeTask that encodes wave files to flac files.
This commit also replaces morituri's EncodeTask with FlacEncodeTask, however, in
morituri, EncodeTask also does the tagging.
FlacEncodeTask will not perform the tagging.
So we will need an extra task for the tagging - this will be added soon.
Meanwhile, do not merge this commit to master yet.
* Add tagging using mutagen.
Replace the gstreamer tagging code with mutagen tagging code.
getTagList is rewritten to return a dictionary of tags, which are then simply
passed to mutagen.
The way it is set up right now is not the best - I don't think it makes sense
for tagging to take place in program/cdparanoia.py ; but this is how the current
code did it.
I suggest that, when we rip out all the gstreamer code, we also move the tagging
to a more sensible place; and then also make the tagging not be an actual
'task.Task'.
* Add gstreamer-less CRC32 version
Only works on wave files at this point. Should not be a problem, I think.
* Use proper musicbrainz tags and ALBUM tag.
* Add mutagen to .travis.yml
