NTNet Relay upgrades
- NTNet Quantum Relays now have simple UI that allows users to manually toggle them on/off. - Implements simplified Denial of Service handling for relays. This will be used by next commit that will add antagonist software. - Relays can buffer and dissipate certain amount of DoS traffic. If this traffic exceeds certain level (configurable via varedit) the relay crashes temporarily. - Relays may be manually reset by using specific button in the UI - Relays are now buildable. They are relatively cheap (circuit board and some cables), but the board requires Data Theory 4 research.
