Move Default Options To Backend

[mdingjan]

Extra issue.

Main change: defaults have been removed from the frontend html pages to the options.ts backend. Also the implementation of the functionality of the 'Restore Options' button has therefore been changed.

Please review this PR by building the extension, trying to find any bugs in the frontend and of course reviewing the code. ;)

Quack!
