C++11 syntax not fully supported

Now that the C++ 11 standard has been ratified, C++ 11 syntax needs to be fully supported in QtCreator.

Some elements are already supported but I often run into the enumerations ending with a comma and the double right angle bracket (for templated templates) showing up as errors.

While it may be a good idea to have a feature to be able to specify the standard syntax via flags (perhaps somewhere in Tools/Options.../something), it should not be required as that is simply a feature and not the current standard.

I understand the rationale behind not making it the default but if it is not then it needs to be advertised expressly as not supporting the C++ standard.
