* Originally taken from my own packaging of Cura on launchpad: ppa:thopiekar/cura - https://launchpad.net/~thopiekar/+archive/ubuntu/cura
* It adds mime-types, which are supported by Cura, to the mime-database, so filemanagers can recognize these files.
* This sharemimeinfo includes currently 3MF, STL and OBJ.
As I upgraded my computer to a developer version of Ubuntu, I noticed that the OpenGL module, which is needed for our workaround, is currently broken.
So I browsed the web and found the reason why it is needed at all and found a alternative.
The reason for the problem is that Qt5 is dynamicly loading libGL.so instead of libGL.so.1, as the OpenGL module loads libGL.so.1.
So if you install the closed-source nvidia drivers it only creates a link from libGL.so.1 to it's binaries and the result is that PyQt5/Qt5 tries to load Mesa binaries together with NVidia binaries.
By importing the OpenGL module you preload the libGL.so.1, but this can also be done directly by using ctypes.
* Replaced the OpenGL fix with the ctypes fix
* Added a TODO
This should be obvious. The thought process was that now we're using the builder instead of making the MeshData object directly, but that has only relevance if you still remember what the old code was.

In layer view, the selection shader is now a uniform-color shader. This shader does not use the vertex colours but makes the entire silhouette the same colour.

The convex hull mesh was made without adding colours to the vertices. This was probably causing the convex hull to appear red on some machines, if red is the default vertex colour. Using meshbuilder makes code maintenance easier and allows us to easily set the colour of the vertices. Hopefully this fixes the issue with the red convex hulls.

Don't know how long we support opening images, but this commit adds them to the *.desktop file for Linux based desktops.
So "open with"-actions will now show Cura for these media-types.
This preference can't be made visible since a string freeze is into effect, but at least a user could go into the .cfg file and set the setting manually.

The default preference for last remembered output file type is set to G-code. So at the first run, it'll have g-code selected by default. In subsequent runs it will remember what the setting was, so the user can set it to something else and it will remember that.
