Sunsetting the offline version?

[pstorch]

I'm thinking about sunsetting the offline version. It's causing confusion, see #282, and the same behavior can be achieved by denying the online map consent.

I guess the real question is the paranoia level of the users. I'm very sympathetic with high paranoia, but thinking about it:

• if you actually care about location privacy, everything about opentracks is insignificant unless you are running a degoogled ROM
• once you are running e.g. CalyxOS, you can deny internet permission in the firewall if you want
• while the permissions model is very useful, the fundamental issue is that you should only run code from places that you trust to act in your interest
• with no maps for the current location, it makes sense to show instead a "configure maps" button, and have that take you to a screen that says "There are two ways to get maps. One is to fetch tiles as needed, which is easy to configure, uses data, and leaks your location. The other is to once fetch a map for a large area and use it offline." or something and then have buttons "consent to fetching tiles (leaks location)" and "fetch map for offline use (large data use at time of downloading)" and have the lower one lead into the download.

and sure, keep settings for later and fancier users. I've pretty much come around to thinking that the offline-only no-internet version isn't really nceessary.
