mdb-export: Add boolean words option (TRUE/FALSE)

Browse Source 
Adds "-B" (--boolean-words) option to mdb-export, which will reconfigure
mdb/data.c to export TRUE/FALSE for boolean values instead of 1/0.  The
option is needed to support BOOLEAN fields on PostgreSQL, which will not
implicitly cast bare 1/0 into a BOOLEAN value.  Value literals are the
SQL TRUE/FALSE, and _quoted_ words meaning true/false and _quoted_
'1'/'0'.  With this flag the SQL TRUE/FALSE values are output, which should
work with several SQL databases.
