Tested on linux under gcc 4.8.2.

The definition of AS_CAN_USE_CPP11 is now in multiple places (though I took it from one of the add-ons). Perhaps it should go in as_config.h?

I was going to also add checking for Clang, but perhaps that can be left for the future.

Did you notice any significant performance improvement when adding these?

Timing the execution of ListFunctions() in the console example, I get 0.000051sec before and 0.000040sec after, which is a ~20% improvement. (I know that that function triggers a handful of operations involving the new functions which take &&)

I plan to time some of my own larger scripts, but won't be able to do that until tomorrow.
