Added IEND chunk to end of generated PNG image.
Requiring cmake 2.6 and newer from now on.
Properly ran constructor of templated superclass (was missing template argument)
CMAKE: Altered some if-tests to use variable names without $\{\} as cmake 2.6 seems to like that better
Qt::MiddleButton replaced with Qt::MidButton as the former isn't supported on Qt-4.6
Refactored local enums to top of file in anonyomous namespace. Local types cannot be used as template arguments, but they were used in a std::vector
Removed a leftover $\{\} in an if-statement within cmakelist
Find-rendering-devices-code in masterjob now peeks into /tmp/.X11-unix
to locate all X servers, and then iterates over these to find which
screens that are accessible. This is propagated into the XML-reply to
client manipulating the master job. Also, a list of rendering devices is
added to the add-job pipeline, and is passed to the job as an
environment variable. What is missing is for IPCGLJobController to make
use of this environment variable.

merged changes from msaa before using new GL context code in IPCGLJobController
Added API-kludge to allow enabling of MSAA on a application-by-
Moved logging callback up to Controller, replaced old Offscreen
rendering code in IPCGLJobController with OffscreenGL.
Merge branch 'signals_and_ipc_and_stuff' into msgbox
messenger_do_roundtrip seems to work, at least it doesn't segfault
anymore.
