Title: Rename Monat to Zeitraum

I found the wording for the timeframe select box a little disturbing:
* the label read `Monat` while the a timeframe (e.g. `1. Quartal`) could be selected
* the repeated `Quartal` strings in the options where a bit unnerving

The commits include changes that
* rename `monat` to `zeitraum` throughout the whole project to name the intended use more accurately
* the `Quartal` options use roman numerals, which I find more readable
* update the timeframe option to either display Monat or Quartal depending
from which optgroup an option was selected

I am well aware that these include rather drastic changes and am curious about your opinion on these.
I deliberately created separate commits to group related changes together.
