abcde -d singletrack.flac should read track names from singletrack.flac.cue

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Rip with abcde -1 -o flac -a default,cue
2. Convert to ogg with abcde -d singletrack.flac

What is the expected output? What do you see instead?

Would expect to avoid CDDB lookup since I already did that in step 1. Also, due 
to some bugs with flac cuesheets, sometimes a different CDDB id is generated, 
so this 2nd CDDB lookup is unreliable. The names are already in the .cue file, 
so this should be merged into the flac cuesheet in step 2.

What version of the product are you using? On what operating system?
abcde-2.6-1.fc21

Please provide any additional information below.

If CDDB from .flac was completely reliable, then this would be only an 
optimization. As it stands, this problem is more serious since I cannot get 
reliable track names from a singletrack flac file.

Two more things:

1. This is a more serious problem, since the .ogg files that get encoded all 
have the wrong cddbid in the metadata.

2. A simpler workaround for the bug would be to trust the cddb id in the flac 
metadata. This would avoid needing to find and parse the .cue file, and would 
also fix the cddbid ogg metadata problem in many cases.
