[meld] Remove dialog use from CVS in favour of logging

    Remove dialog use from CVS in favour of logging
    
    These were low-level errors that indicated broken things in the CVS
    repository, not general problems in Meld. There's little point in
    displaying such errors to the user, so logging is more appropriate.
