Sort the different sections and packages

The order in which UX defined the different sections are:
- Installed Cura Plugins
- Installed Materials
- Bundled Plugins
- Bundled Materials

All packages need to be order at least by section, but I also took
the liberty to sort the packages in these sections by Alphabet.
