Round-trip AUTOINCREMENT in SQLite parser (#158)

Currently, the SQLite parser sees the AUTOINCREMENT keyword and sets
the column flag is_auto_increment, but the SQLite Producer will not
write the AUTOINCREMENT keyword unless extra.auto_increment_type is
'monotonic'.  This breaks round-trip by the AUTOINCREMENT keyword
getting lost.
