Support for Color Themes

I have added an option to change the color theme of MQTT.fx.
The choice is: Light, Dark (experimental) and Custom:




You can start a new custom theme by choosing “Create custom CSS template” which will create a (light) color theme css template. You will be prompted with a dialog showing the actual location of the created template. A click on “Edit” opens the selected CSS file in your preferred Editor.
