Improve logging

[revett]

Current have pretty poor logs, lets improve them.

1. Unable to select and copy within log view pane
2. sync: conditional write support verified does not get logged when test/save connection in settings, is this not shared code?
3. Make change(s) better
4. Include what actually changed on vault refresh and sync
5. Make the log lines more human when reading
6. Is <ts> <level> <msg> really the best format?
7. Update tagline subheading in settings page
8. Amount of logging is really low, e.g. a single line for sync, what about start / progress / compete / error
9. Change copy of Geode: click to sync hover copy on status icon
10. Make Geode: Sync command copy more useful
