[Qt-creator] Dev: Increasing requirements for building Qt Creator 4.2(master)

[Eike Ziller]

I’d like to propose requiring the following for building Qt Creator 4.2 (currently “master” branch):

MSVC2015
GCC 4.8
Qt 5.6.0

These compilers have many fixes for C++11 code (e.g. move semantics is basically unusable in MSVC2013).
As far as I can see we do not loose support for any relevant platform version.

Regarding Qt, Qt 5.7 is out, and when Qt Creator 4.2 releases there will probably Qt 5.8, so it should be fine to up the requirements to Qt 5.6.

Comments welcome, you can also cast your vote on https://codereview.qt-project.org/163933

Br, Eike
