* modules/other/gail/*.[ch]: Remove relocations from the atk factories. Remove unused gail_foo_new() functions. Fix object instantiation to be derivation safe by moving initialisation code from the removed gail_foo_new() functions to the AtkObjectClass::initialize implementation. Bug #505226. svn path=/trunk/; revision=19237
