Add ImageEncodeTask to encode a disk image to a different profile
and directory.
* morituri/common/encode.py:
Add lossy encoding profiles for mp3 and vorbis.
Rename muxer to tagger since that's what we use it for.
Do progress probe after level to make sure we get samples for
offsets.
* morituri/rip/image.py:
Add rip image encode command.
Add a test() method to the profile so we can warn about bad
flacenc versions.
Encode track number and count, and release date, if possible.
* morituri/rip/cd.py:
Fix another off-by-one error in the tag encoding.
* morituri/program/cdparanoia.py:
* morituri/rip/cd.py:
Clean up the temporary unencoded file.
Pass profile as objects to tasks, so that temp files have the right
extension.
* morituri/program/cdparanoia.py:
Add encoding profiles, kept simple for now as a class and
subclasses. Use them to encode. Calculate peak level while
encoding, compared to EAC and replaygain's value.
* morituri/rip/cd.py:
Use the encoding profiles, ripping with the right extension.
Add a --profile parameter for it.
