support all of C++11 in Cactus or the Einstein Toolkit

We are currently allowing a subset of C++11 to be used in Cactus and the Einstein Toolkit. Looking at configure.in the supported features are:

the auto specifier
C++ lambdas
C++ range based for

To support all interesting features one would need at least icpc 15 as well as g++ 4.8 and clang 3.3.

== Compiler support ==

The major compilers provide the following information on the features they support:
