#697 PyTango.server.run does not accept old Device style classes

[Tiago Coutinho]

PyTango.server.run does not accept old style (DeviceClass, Device) as parameter.

example:

class OldStyleDevice(PyTango.Device_4Impl):
    pass

class OldStyleDeviceClass(PyTango.DeviceClass):
    pass

class NewStyleDevice(PyTango.server.Device):
    pass

run([NewStyleDevice, [OldStyleDeviceClass, OldStyleDevice]]

Will fail. Here is a stack trace:
