slice2cs generates invalid namespace qualification

[pepone]

The following Slice code generates invalid C# code with both 3.6.4 and 3.7.1

module test
{

class Point
{
};

};

module Foo
{

module test
{

module Bar
{

interface Canvas
{
   void drawPoint(test::Point p);
};

};

};

};

The generated code will lookup for Point in Foo::test rather than ::test

namespace Foo
{
    namespace test
    {
        namespace Bar
        {
            [_System.CodeDom.Compiler.GeneratedCodeAttribute("slice2cs", "3.6.4")]
            public interface CanvasPrx : Ice.ObjectPrx
            {
                void drawPoint(test.Point p);

We should always use global:: for full qualified names
