Dropping MSVC2012 as per

http://lists.qt-project.org/pipermail/development/2016-March/025129.html

would remove the block from being able to use template aliases according to

https://msdn.microsoft.com/en-us/library/hh567368.aspx

I don't have ready access to all the other compilers and versions we support 
but I think this would allow potential use of:

* template aliases
* raw string literals
* delegating ctors

Marc, you likely know compiler limitations much better than I do, do you have 
any inputs on this please?

Cheers,

Sean
