Add option to enter static location of the computer #165
Description
Problem
Mozilla has closed its location service (https://discourse.mozilla.org/t/retiring-the-mozilla-location-service/128693) that geoclue2 was using. Google location service requires a paid API key. IP based location resolution is unreliable in certain situations, because it depends on many external factors. This creates issues, like automated theme switching based on sunrise/sunset times not working realiably.
Proposal
For desktop PCs, that usually stay at the same place, this can be solved by creating a /etc/geolocation file with static coordinates (as per man geoclue). This could be available as an option in the Settings app, with the possibility to switch from automated location to static location. The required coordinates can be easily obtained with a service like OpenStreetMap.
