Starfall Tactics WIP: Research Station, Carriers and Gravity Modules

[Relampago]

Another stage in Starfall Tactics' development has just begun - so, it's time to add some awesome stuff: Carriers, gravity weapons and new stations for discovery. And that's only the beginning - we are about to implement other great features.  **Research Station** is an extremely helpful feature for the House (guild): it allows to generate research points which players can spend on some useful stuff, making them protect bases with more diligence. **Carriers** are giant ships which can carry other small vessels - squads of bombers, fighters and other special ships. Too fast and small to be even targeted by large spaceship weapons, they can be a real problem, and that's without telling the Carrier itself is a huge well-protected construction.**Gravity stuff**appeared to be not a very easy thing to add due to our in-game physics: one wrong impulse and it can become an ultimate weapon, crushing enemy ships in a second. So, we started it from one basic module, pushing enemy ships to the center of area of impact.
