Rework of systray statuses

- 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.
