[SailfishOS] Offline mode
Add an offline mode to Whisperfish. Loosely related to #179. Use cases:
- Traveling (use data only sparingly)
- Battery saving (IMHO wf is really low power, but still)
- Whisperfish development (don't bother Signal servers with reconnections)
Approximately what it takes:
-
Add Settings item -
Make the connection logic obey the setting -
Add cover page indicator (see #196 (closed)) -
Add main page indicator -
Add session page indicator
