Added following methods to osgDB::Archive in support of work by Fradley Anderegg on .zip archive support:

Browse Source 
/** Get the file name which represents the archived file.*/
       virtual std::string getArchiveFileName() const = 0;

       /** return type of file. */
       virtual FileType getFileType(const std::string& filename) const = 0;

       /** return the contents of a directory.
       * returns an empty array on any error.*/
       virtual DirectoryContents getDirectoryContents(const std::string& dirName) const = 0;

Added implementations of these new methods into src/osgPlugins/osga/OSGA_Archive.h src/osgPlugins/osga/OSGA_Archive.cpp
