Adding the first version of KdeEduGlossary. This class will be shared by
Kalzium and KStars, at least.
Currently, we have three classes:

GlossaryDialog: The dialog, derived from KDialogBase
GlossaryItem: An item, consists of a name, the content
              potentially references and pictures, stored
			  as QStringLists.
Glossary: This class stores and manages the items. It
          also has the xml-parser.
