From 7ef5d0b10ae214f7c58aa77fb84547be1388f2d6 Mon Sep 17 00:00:00 2001
From: Kitsune Ral <Kitsune-Ral@users.sf.net>
Date: Mon, 25 Dec 2017 17:20:27 +0900
Subject: Now really switching to the new toolchain: C++14, GCC/Clang 5, Qt 5.6

Also a bit of code tightening with some C++14 (but not only) things.
