Well - I am still playing around with difficulty and tx fees. I also left the max block size unchanged for now as I don't see any benefit to reduce it. Currently, the coin would support approx. 160tps i.e., 4 times higher than Bitcoin which is still small compared to real world microtransaction rates.

Nevertheless, I updated the code base w.r.t:
- max. coins corrected to 42 007 680
- added a option to dump block chain statistics
- added a few checkpoints for current block chain + reenabled code that does the checkpoint checking
- new icons (finally distinguishable from Litecoin)

The update is not mandatory but improves security.
