We already mark peers as misbehaved if they returned invalid signatures, but this wasn't sufficient when multiple copies of the same invalid block exist on the network (e.g. after a hard fork). In these cases, we need to be more proactive to avoid syncing with these peers, to increase the chances of preserving other candidate blocks.
Previously, a peer would be continuously considered not 'old' if it had a connection attempt in the past day. This prevented some peers from being removed, causing nodes to hold a large repository of peers. On slower systems, this large number of known peers resulted in low numbers of outbound connections being made, presumably because of the time taken to iterate through dataset, using up a lot of allKnownPeers lock time.
On devices that experienced the problem, it could be solved by deleting all known peers. This adds confidence that the old peers were the problem.

- Show "Minting" as long as online accounts are submitted to the network (previously it related to block signing).
- Fixed bug causing it to regularly show "Synchronizing 100%".
- Only show "Synchronizing" if the chain falls more than 2 hours behind - anything less is unnecessary noise.
Reduced AT state info from per-AT address + state hash + fees to AT count + total AT fees + hash of all AT states.
Modified Block and Controller to support above. Controller needs more work regarding CachedBlockMessages.
Note that blocks fetched from archive are in old V1 format.
Changed Triple<BlockData, List<TransactionData>, List<ATStateData>> to BlockTransformation to support both V1 and V2 forms.
Set min peer version to 3.3.203 in BlockV2Message class.
Bump v3 min peer version from 3.2.203 to 3.3.203
No need for toOnlineAccountTimestamp(long) as we only ever use getCurrentOnlineAccountTimestamp().
Latter now returns Long and does the call to NTP.getTime() on behalf of caller, removing duplicated NTP.getTime() calls and null checks in multiple callers.
Add aggregate-signature feature-trigger timestamp threshold checks where needed, near sign() and verify() calls.
Improve logging - but some logging will need to be removed / reduced before merging.
