Semantic MediaWiki 0.2

From the RELEASE-NOTES
Changes by mak (0.2 (=0.2a), 4 Dec 2005):
 * Attribute values are now correctly stored and retrieved.
 * Special SearchTriple greatly enhanced, such that queries for attributes become possible (including unit conversion).
 * Links from attributes in infobox to the new search form.
 * Major code cleanup: SMW_AttributeStore.php now is called SMW_SemanticData.php and managemes all types of semantic data, including printout and storage. SMW_Hooks.php was freed of all code with similar purpose. Look-up of attribute types was moved from SemanticData to Datatype.
