Summary description:  Coloured boxes, for LaTeX examples and theorems, etc

Announcement text:
 - bug fix (#88): 'parskip' and 'noparskip' had side-effects for the box content
                  in combination with 'height fill' and 'parbox=false'

 - bug fix (#90) in library 'documentation':
   initialize 'doc description' for every docXXX to be empty

 - Internal box counter renamed to remove warnings when using \includeonly

 - library 'documentation':
   * major code overhaul to support simultaneous documentation of
     similar commands, environments, keys, path operations (#89).
   * Note that the new code reserves a small additional amount of vertical space
     for documented macros which may result in changed page breaks.
   * Note that documentation heads are now embedded inside a 'raster'
     which requires other customizations for vertical space (if needed)
   * new macros and environments: 'docCommands', 'docEnvironments',
       'docKeys', '\tcbmakedocSubKeys', 'docPathOperations'
   * new options: 'doc index' (#91), 'doc name', 'doc parameter',
       'doc keypath', 'doc sort index', 'doc no index',
       'doc raster command', 'doc raster environment', 'doc raster key',
       'doc raster path', 'doc raster'
   * additional option setting for: '\docAuxCommand', '\docAuxEnvironment',
       '\docAuxKey', '\docValue', '\docColor', '\docCounter', '\docLength'
   * superfluous and undocumented opton 'color frame' removed (#94)
   * '\refAux' and '\refAuxcs' are not longer colored, if colorlinks=false (#95)

 - library 'listingsutf8':
   safeguard against compiling with other engines than pdf(la)tex (#92)

 - library 'fitting':
   '\tcbfitdim' is described in more detail (#96)

 - library 'poster':
   poster width and height caveats described in more detail (#98)
