Change subject: Add FakeSafeHtmlTemplatesMaker
......................................................................
Add FakeSafeHtmlTemplatesMaker
Similar to FakeMessagesMaker and FakeCssMaker, this class allows Java
tests to create instances of SafeHtmlTemplates without needing to call
GWT.create()
JUnitSuite updated accordingly.
