media-gfx/opencsg: new version 1.4.0 to fix two bugs.

This fixes a version bump request from one of our users, and also a
build failure. Version 1.3.2 tried to link with QtGui, even though
that wasn't a declared dependency, causing the build to fail when it
was missing. The new v1.4.0 doesn't seem to have that problem, so the
build failure should be gone.

In the process, the ebuild was updated to use EAPI=6 and
qmake-utils.eclass.
