Subject: [PATCH] Add option to request BOM write

Before, we always write BOM at the beginning of UTF files. Not all tools
understand BOM files. psql knows about it only since PostgreSQL 9.0, so our
sql files are not usable with psql 8.4 and before. So, this option is
available to allow a user to decide if he wants BOM or not.

Implements #283.
