nuvexport won't process a file specified with --infile unless it has a cutlist

[schachte@…]

If the nuvexport config file specifies that a cutlist is required, then the phase of the code that loads info from the database ignores all recordings without a cutlist. But if the recording to export is specified on the command line, and that recording does not have a cutlist, then it won't be included in the info loaded from the database, so myth mistakenly reports that it does not exist. This patch just ignores the option to require a cutlist if a file is specified on the command line -- perhaps not the most elegant fix, but it's simple and it works.

(In [12602]) ignore --require_cutlist if the file was requested via --infile. closes #2967, though not by the patch since it was against the wrong svn.
