Logging

[Thorium]

We could have some kind of easy way to add logging capacities.

For example like FsSql does:

Hmm. I'm not sure if this is needed as we already have the events in place... Maybe also send some events on failwith-cases, or do we assume that user wraps things with try-catches to log exceptions? And how about network-outage to database server?
