sisu harvest, introduce module along with header syntax addition & modification

* sisu markup, additional header and new format rule:
  * @creator: / @author: header field, introduced author name format rules
    for more usable metadata harvesting: surname comma other names, additional
    authors separated by semi-colon
  * param added meta-tag, @topic_register: formatting topic levels are
    separated from sub-levels by a colon, a semi-colon separates main topics
    if there are multiple topics at lowest sub-level, a pipe can be used to
    create multiple headings

* harvest module, harvests metadata from document set currently extracts: (i)
  authors and their writings from document set; (ii) topics and associated
  writings from document set (topics use topic_register header). harvest
  (when run against documents common to a directory of a site) extracts
  metadata and organises the documents on a site by author and topic
  information provided (there is a new "topic_register" header, with
  formatting rules similar to those of the book index), results are placed in
  [output_path]/sisu_site_metadata.
    sisu --harvest *.sst
  * by author (see change in param @creator: / @author: header field)
  * by topic / subject index (see addition in param of @topic_register:
    header field)
  initially there should be an example samples here:
    http://www.jus.uio.no/sisu/sisu_site_metadata/harvest_authors.html
    http://www.jus.uio.no/sisu/sisu_site_metadata/harvest_topics.html
  together with update markup source files

  The authors and their writings list will be made to take on a more
  biblographical form, with the use of additional fields as required.
  (concept example, suitable for medium sized sites [to remove size
  constraint: implement SQL equivalent]) make feature more robust

* css, for harvest output added

* remote placement of sisu_site_metadata (output produced by metadata harvest)

* sisu markup, update document samples accordingly

* tidy copyright marks in program headers, remove repetition of dates

[version bump because formatting rule introduced to author / creator header -
where new site metadata harvest feature is used, (at present changes changes
should not be noticed except when using metadata harvest)]
