v1.4.0

Lots of new stuff. Most important updates are improved game engine and space adventure which starts being kinda fun :)

• Added new honours.
• Store network keypair to be able to have consistent PeerId across sessions. This allows us, for instance, to bookmark friends (in the future) and resend open challenges and trades automatically (done in this version).
• Added a new asteroid upgrade, the space cove, and a basic space cove panel. It is now possible to visit peers asteroids and play on them.
• SSH: server automatically closes client if there is no input for 2 minmutes.
• Several improvements to the game engine, main one being a recalibration of tactics and improved shoot stats modifiers.
• Refactored code to unify spaceship and asteroid upgrades to single struct and improved build/upgrade interface. Also increased upgrades costs and duration.
• Cleaned up and improved performance of space adventure, plus a little (and dangerous) surprise ;)
• Added pending messages in swarm panel tab and a make chat selectable list to allow to see past chat messages.
• Refactored Ui panels and split UiKeys into different namespaces.
• Added new spaceship components: charge unit and shield, corresponding upgrades and use during the space adventure.
