First round of fixes
Further changes
Futher work on the proposal sync
Push now also only does a differential push

- send uuids of events to be pushed together with timestamps to the other instance
- other instance removes events that are already up to date or locally created from the array
- sends the remaining uuids back
- first instance initiates the push of events that were not filtered out
