Add seamark:notice:orientation

[PetersonGIS]

Eventually we will want to have seamark notice orientation data in the db. Note: not crucial for proof-of-concept.

Should be fixed with 1468ad0. Data will be available after tonight's import.

I am missing something obvious.

The problem has been that one of the attributes on a seamark:notice, function, is a reserved word in SQL. The unexpected result is that the value of function has been getting through and appearing in the popup inspector but the next field in the query, orientation, disappeared with the error.

At a bit of a loss as to what the best thing to do is but for now I am replacing function with the S100 name, fnctnm. In the case of the buildings and landmarks queries I'll use functn.

A similar problem arose with the use of the attribute name group, which I replaced with signal_group, and which I'll revisit and log somewhere.
