and call the respective slot

And refactored ffunctionality to common function which uses a bool to
determine connection type

* Added variable for flags to pass to the Qt finder. Use
NO_DEFAULT_PATHS when no system installed Qt should be used.
keep flags empty if the system installed version is to be used

added default search path for Qt on OSX to find Qt distributions from our repository if cloned to ~/sw

fix to find Qt5.9 RC

See merge request !19

made the Qt finder look for the newer Qt5Core_VERSION variable and set Qt5Core_VERSION_STRING to Qt5Core_VERSION if it is found.
This is needed since qt59 does not set the Qt5Core_VERSION_STRING variable properly, which is fine, as this variable is deprecated anyways.

Revert "Merge branch 'fixVSIIcon' into 'master'"

Feature glut primitives

See merge request !14

ran cppcheck and fixed some warnings

be glutFree

DrawModes constructor is now explicit which causes some changes:
e.g. if you used ACG::SceneGraph::DrawModes::TEXCOORD_PER_VERTEX
you now have to use
ACG::SceneGraph::DrawModes::DrawMode(ACG::SceneGraph::DrawModes::TEXCOORD_PER_VERTEX)

Use ACG Torus implementation in glutPrimitiveNode

TODO: Teapot and Torus, rest should be working

Added some missing primitives that were rendered using glut (behavior
should be similar): Dodecahedron, Icosahedron, Octahedron and Tetrahedon

(except for Torus and Teapot htey are still todo)
