Technology Rebalancing

[Clashsoft]

• Added new tech tags: weaponry (physics) and shipmaking (engineering)
• Cleaned up technologies.ts
• Adjusted costs of all techs to be linear and according to the level in the tech tree.
• Adjusted variable modifiers of many techs to be linear (e.g. -5%, -10%, -15% instead of -5%, -10%, -20%)
• Added new technologies: biology_specialization, economy_specialization, building_specialization, system_specialization
• Removed technologies: computing, construction, demographic, engineering, production, faster_ship_construction_1,2,3
