Erroneous Column Comparisons Reported

In some cases, a column attribute may be specified in a number of different, but equivalent, ways via the schema interface. For example, a NULLable column might have the "not null" specification omitted, specified with no value, or specified with an explicit value of FALSE. The current comparison code does not take that into account.

The attached patch adds additional checking for these cases. It also adds explicit identification of the attribute(s) on which a difference was detected to add a little clarity.
