* morituri/program/cdparanoia.py:

cdparanoia can hang indefinitely on scsi read errors.
	  For example, on some drives, when trying negative offsets.
	  Notice them, count them, and fail after 100.
	* morituri/test/test_program_cdparanoia.py:
	* morituri/test/cdparanoia.progress.error (added):
	  Add a test for this output.
