Description

The size is reduced by ~500MB for both ubuntu and debian.
Other than that, it switches from Qt4 to Qt5, as Qt4 end of life was DEC 2015 (no announce was made since, though).
It introduces "ninja" to ubuntu image, so that the cmake build time is slightly improved, but "make" build is still tested on debian.
