[API CHANGE] OfficeBean: remove deprecated com.sun.star.beans classes

<https://wiki.openoffice.org/wiki/Documentation/DevGuide/JavaBean/The_Internal_Office_Bean_API>:
"Prior to OpenOffice.org 2.0 all Office Bean classes were in the
com.sun.star.bean package.  As of OpenOffice.org 2.0 the classes are contained
in the com.sun.star.comp.bean package.  The classes of the com.sun.star.bean
package are still contained in the officebean.jar but they are deprecated.
Further development and bug fixing will occur only in the com.sun.star.comp.bean
package."
