Subject: (truncated): Added "style" argument, so that at least Python users
 can choose which output style they want (truncation at beginning, middle or
 end of the string).  (export_format): Expose following handlers to Python:
 FormatTransactions, FormatEntries, FormatXmlEntries, FormatAccount,
 FormatEquity.
