Berthold Stoeger 5f91c69f9c statistics: create themes on demand
Create the themes only when needed (singleton pattern). If
the themes should do more than colors, such as for example
fonts, it is not clear whether that can be done before main()
runs. By creating the themes on demand, the Qt UI should
be initialized in the constructors of the themes.
