Fix a series of issues found during testing. This is the patch provide

to Yaco on 2011-03-19, and committed on branch/yaco/idsubmit as [2896].

   * Extraction of Title which don't have the draft name on a separate
     page fails.  See for instance this example:
     http://www.ietf.org/staging/draft-ma-cdni-publisher-use-cases-00.txt
     The regex should maybe be updated to permit but not require a newline
     before the draft filename:
     '(?:\n\s*\n\s*)((.+\n){1,2}(.+\n?))(\s+<?draft-\S+\s*\n)\s*\n'

   * If there are blank lines before the start of the author list on the
     first page, the author extraction will fail.  This sometimes happens
     when there's junk at the start of a draft, see for instance
     http://www.ietf.org/id/draft-ietf-mpls-tp-process-00.txt .

   * Sometimes the Authors' Addresses section lists authors with the same
     workplace address on the same line: "Sam Spade and Joe Smith".  This
     needs a fix in the author extraction code.

   * Sometimes the order of first name, surname is different on the first
     page and in the author list, and sometimes the surname is uppercase
     in one place, but not in the other.  This also needs a fix in the
     author extraction code.

   * The header stripping code had a bug, where multiple blank lines could
     be replaced by a single blank line in the stripped text, which could
     mess up title extraction.

   * Title space normalization should be done also for titles from the
     'unusual title format' code branch of the title extraction code.

   * Company names on the first page are sometimes rendered with different
     case than in the Authors' Addresses section.

   * Some drafts list the draft filename _before_ the title, rather than
     after the title.  Permit this too. Covered in the patch.

   * Spanish names can be shown as either
	<given_name> <fathers_first_surname> <mothers_first_surname>
     or less formally as
	<given_name> <fathers_first_surname>
     If the first form is used in the Authors' Addresses section, but the
     second form (with the given name possibly abbreviated to its first
     letter) the author extraction will fail.

   * Drafts containing tabs will be caught by idnits during I-D submission,
     but in case the drafts.py module is used independently from idnits,
     convert tabs to spaces in order for the author extraction and other
     methods to work as expected.  Example: recently submitted draft
     draft-bergeron-payload-rtpfec-rs-00.txt.

   * Found a draft with a previously unhandled header/footer format:
     draft-fang-mpls-tp-oam-toolset-01.txt.  Tweak needed for header/footer
      stripping.
