Classes must defined in order or else Protofile type XXXX unknown is thrown

[GoogleCodeExporter]

If I define two classes in the proto file like so:

message TestClass {
   optional BlahClass blah = 1;
}

message BlahClass {
   optional string text = 1;
}

It will throw the error "Protofile type BlahClass unknown!". I would expect
it to be able to tell BlahClass is defined later in the proto file.

Another example:
message TestClass {
   repeated TestClass test = 1;
}

This also throws the error "Protofile type TestClass unknown!"
