[Feature request] Export settings

[WiseOlli]

Hi, many thanks for the great app!

It would be really great if you could export and import the settings.

For example: I have inserted 15 websites for the "Web pages and searches".
If I now buy a new cell phone, I would have to set up all these search engines again and manually enter them all individually.

It would be good to be able to export the settings to a file sometimes and import them again if necessary.
