Patch-fix #6

- Fixed the appearance of contracts whose target is in an unreachable sector
- Now you can not take multiple contracts for the destruction of the station
- Now a reward for killing a pirate is given in the event that you have dealt him at least a little damage
- If the pirate base for which the contract appeared has already been destroyed - the contract now disappears from the chat
- Fixed a network error that could provoke a crash
- Improved the sector generator: now the dynamic disappearance of wormholes and sectors will not affect the connecting sectors (as a result, we will get fewer isolated sectors)
- Disabled New Year music at stations
- Fixed UI layering in settings menu and main menu
- Added volume setting for NPC replicas
- Fixed a bug in the starting tutorial (stuck software installation menu)
