Stopped the authoring using the DTOs as a way of converting the data coming from Flash. Using the DTOs caused the WDDX null values (e.g. -1111111) to be written to the database.
Improved the special NULL handling code for WDDX processing. Learning design DTOs now use the convertToBlah utilities in WDDXProcessor. Also covers changes made by Mai recently.
Changed authoring storeLearningDesignDetails and storeTheme to use standalone servlets. The struts actions can't take the WDDX packet from Flash as a POST body. Also updated DOLLY to 4.0.2 so updated all the core project jars.
