Missions (#67)

* Mission resource type * Add forfeited state, and validate transitions * WIP checking and updating mission status * WIP * Connect MissionController to Player * Docs for `MissionController` * Add planets to StarSystem * Add planets_with_systems lookup from galaxy * Logic to create a random delivery mission * WIP mission computer window * Connect missions button in landing screen * Change planet -> star system lookup into a weak ref, like systems in galaxy * No need for `galaxy` parameter to `create_random_delivery_mission` * Enable missions on some more planets * Missions window * Add cargo to hold when starting mission too * Fix out of bounds on pick_random_special() * Fix money display * %i totally screws things up, whoops * Set tooltip text when button is enabled * Fix mission description layout * WIP debugging why mission success isn't working * Rename "missions window" to "mission computer window" * In-game mission log UI * Fix `toggle_mission_log` action * Change diplomatic "pouches" to "parcel" * Remove mission cargo on failure * Fix mission success causing mission failure * Memoize generated missions on PlanetInstance So they don't regenerate every time the player lands. * Ensure `MissionController` is saved * Convenience functions for serializing dictionaries with resource keys * Fix mission loading and saving * Rush delivery mission type * Fail missions past their deadline * Re-check mission failure when calendar updates * Add to message log when missions succeed, fail, etc. * Note the limitation of _randomly_walk_systems * Increase deposit of rush deliveries too * Add a couple more special commodities
