Refactor Settings Dialog with Confirmation Dialog

[NXXR]

Refactor the settings dialog that is used in the goup filter editor into a component.

As a pop-up dialog for settings with a confirmation dialog on close wheter to discard changes made will be necessary in many components in ESID in the future, i.e.:

• Compartment filter editor
• District map settings
• Heat legend editor
• NPI editor

Implementation ideas:

• Component providing the main pop-up and the confirmation dialog.
  • receives children as props to render.
  • holds state whether children changed and passes function in props to change state (i.e. mark child components dirty/changed)
