Make reload button clear webstorage

[Nereboss]

Feature request

Make the reload button not only reset the maps and settings but also the web storage as some parts of our application are stored there (e.g. the metric templates or custom views).

Description

As a user, I want the reset button to clear the web storage so that it feels like a real reset button because currently some stuff from the old session is kept.

Open questions

Should we include settings for the reset button what it will reset?
