[Development] C++11 initializer lists in Qt 5.7

hasn't happened. So we're doing it piecemeal]

In specific for initializer_lists, the only compilers now with problems is M
MSVC 2013 RTM and SP1. SP2 contains a fix that allows us to enable the 
functionality.

But since MSVC does not keep binary compatibility between versions, we should 
be allowed to use initializer_lists in our ABI.

Any disagreements?
