(truncated): Simplified this method, and added schemes for truncating

Browse source 
at the beginning and middle of a string (neither of which seems better
than truncating at the front).  (output_xml_string): Change xml_string
to output_xml_string, for simplicity's sake.  Also, < and > are now
output as &lt; and &gt;.  (format_last_entry): Use output_xml_string
for the account name as well as the code, payee and note.
