#48 GEDCOM export lacks HEAD/TRLR

[choess]

Exporting GEDCOM to a text file from either the BKEdit or jLifeLines UI creates a GEDCOM file that has neither a head nor a trailer, and hence cannot be re-imported without hand editing. I've poked around a little trying to find the problem, but my knowledge of the codebase seems to have dropped to absolute zero in the past several years. Do the FSDB->Rawdb functions handle all writing to text files?
