umbrello/codegenerators/idl/idlwriter.cpp

- In functions isOOClass and writeClass, on comparing against known
  stereotypes accept stereotype prefixes other than "CORBA".
  Reason: IDL v4 separates the language from CORBA. Several known tools
  use stereotypes prefixed with "idl" instead of "CORBA".
- In function defaultDatatypes add missing types "long long",
  "unsigned long long", "long double".
