Further fixes to enable composer autoloading

With this release, RDFIO and all special pages work, with the following caveats:

• A known issue with WikiObjectModel

• You now have to configure the same database connection information as in LocalSettings.php, also in <wiki>/extensions/Rdfio/RDFIO.php ... meaning that you have to modify this code accordingly:

  $smwgARC2StoreConfig = array(
          'db_host' => 'localhost',
          'db_name' => 'CHANGETHIS',
          'db_user' => 'CHANGETHIS',
          'db_pwd' =>  'CHANGETHIS',
          'store_name' => 'arc2store', // Determines table prefix
  );

Minor fixes for autoloading via composer

v2.0.1

Harmonize version format (use leading 'v')

Updated to work with SMW 2.3.x-2.4.x

This version contains updates to work with SMW 2.3.x-2.4.x, and is aimed to be installable via composer and packagist.org. The latter still needs to be setup and tested, so don't expect things to work out smoothly just yet.
