Changes 0.9.0:
   * Images/Sounds can now be dragged into a matrix cell.
   * Fully implemented date and number formatter inspectors (these
     classes still need work in GUI).
   * Added warning panel if the user attempts to edit a .gorm file
     created with a newer version of Gorm
   * Modified data.classes format so that only those actions
     specifically added to FirstResponder are listed.
   * Greatly improved gmodel importation. (experimental)
   * It's now possible to add methods to classes which are not custom.
     This allows the user to add actions which may have been added to
     those classes by categories.
   * Completely new header parser implemented.
   * Improved cut/paste.  It's now possible to use cut/paste from
     almost anywhere.  The class editor now fully supports it.
   * Improved implementation of some of the InterfaceBuilder framework
     classes.
   * Object editor will now remove all instances of a class that has
     been deleted from the class editor.
   * The class inspector and the classes view will now apply stricter
     rules to names of actions and outlets to ensure that they are
     properly entered.
   * All inspectors work perfectly with customized colors.
   * Fixed a number of bugs.
