make start page configurable

[jwaldmann]

Hi.

This add-on looks very useful, cf. raptor2101/Mediathek#108 (comment)

It seems that this add-on's browser always starts with google.com. How can I change this?

Ah, reading the source, I found that I can put a line

 <setting id="home_page" value="https:..." />

into /storage/.kodi/userdata/addon_data/script.web.viewer/settings.xml
