0.6.0 - Adrastea

This release fixes and improves the following:

• Improved catching up. Previous build would sometimes fail to catch up or stop for no obvious reason. This should now be fixed
• Fixed the VM. This caused issues with processing certain contracts.
• If a connection fails to a peer it will continue trying for a couple of times.
• Peers can be pushed towards clients even when the clients hasn't asked for it. Previously builds would ignore the peer server's peer message.
• Fixed retina issue
• Faster startup time

Additionally I've decided to give some flavour to the releases; names of satellites.
