First part of the merger of fixed artefacts into unrandom artefacts

(further changes will be much smaller).  Breaks savefile compatibility,
and bumps the major savefile version up to 6.

Some changes made to some tiles files, but it hasn't been tested with a tiles
build.

Overview of changes:

* Unrand artefacts are now defined in art-data.txt and is turned into
  C code via util/art-data.pl.  This has the dual advantage of being
  more readable by humans, and that if the unrand data structure
  changes then you can just change util/art-data.pl and regenerate
  the C code rather than having to change some 70 different C structs
  by hand.

* util/art-data.pl automatically updates NO_UNRANDARTS, and also
  automatically generates an enumeration of all the unrands which are
  equal to their item.special field.

* randart.cc and randart.h have been renamed to artefact.cc and artefact.h,
  since the files covers all types of artefacts, and the differences
  between randarts, unrandarts and (former) fixed arts have been
  minimized since the terms were introduced.  Also renamed unrand.h to
  art-data.h

* The brands and resistances of former fixed arts are now handled via
  artefact properties, but the rest of their special behaviours are still
  hardcoded.

* Unrandarts are now distinguished between normal and "special",
  with the special ones currently just being identical to the list of
  the formed fixed arts.  Special unrandarts are randomly generated less
  often than normal unrandarts, can be generated in the Abyss if they've
  been lost, can't be picked up by monsters, and can't be affected by
  Tukima's Dance.
