Massively refactored everything related to entity inventory management
We are no longer recalculating mass by iterating over the entire inventory any time anything changes, for example
Gear is explicitly associated with hardpoints in the entity code
This did introduce some bugs, will clean those up tomorrow
We now have a context menu UI for in-game actions, right click on an item to activate
Database view has a progress bar (finally!)
Data structures for Megacorps and loadouts
Towing task complete? needs testing
Agent behaviors are no longer hard coded but instead created by equippable control modules
Game Context has a job system which assigns appropriate tasks to drone control modules
Game Context was creating an empty OrbitalEntity for every planet; this was an ugly hack so I refactored it, as well as refactoring some object references to GUIDs as they should be
Ship locomotion now accounts for tangential velocity, slows down properly with terminal phase separated into velocity matching behavior
Tech tree properties panel visualizes parents and children correctly
