Need to check custom column name in populate_comment_column

This plugin currently mistakenly populates the comment karma in all custom columns in the comment admin panel, not just its own custom column.

The fix is a check for the correct custom column name in the function populate_comment_column

Need something like the following at the start of the populate_comment_column function:

/* fix to check custom column */
if ( $column != 'comment_karma')
        return;
