* Remove weapons, armor, misc, itemCommon, itemTyps datadict singletons
- removed loader calls from d2app
- removed the HeroObjects singleton from `d2core/d2inventory`
- added an InventoryItemFactory in d2inventory
- package-level functions that use data records are now methods of the InventoryItemFactory
- renamed ItemGenerator in d2item to ItemFactory
- package-level functions that use records are now methods of ItemFactory
- d2map.MapEntityFactory now has an item factory instance for creating items
- fixed a bug in unique item record loader where it loaded an empty record
- added a PlayerStateFactory for creating a player state (uses the asset manager)
- updated the test inventory/equipment code in d2player to handle errors from the ItemFactory
- character select and character creation screens have a player state and inventory item factory
- updated item tests to use the item factory
* minor edit
* Removed d2datadict.Experience singleton
added a HeroStatsFactory, much like the other factories. The factory gets an
asset manager reference in order to use data records.
* removed d2datadict.AutoMagic singleton
* removed d2datadict.AutoMap singleton
* removed d2datadict.BodyLocations singleton
* removed d2datadict.Books singleton
* Removed singletons for level records
- removed loader calls in d2app
- changed type references from d2datadict to d2records
- added a `MapGenerator` in d2mapgen which uses thew asset manager and map engine
- package-level map generation functions are now MapGenerator methods
- `d2datadict.GetLevelDetails(id int)` is now a method of the RecordManager
* remove SkillCalc and MissileCalc singletons
* Removed CharStats and ItemStatCost singletons
- added an ItemStatFactory which uses the asset manager to create stats
- package-level functions for stats in d2item are now StatFactory methods
- changed type references from d2datadict to d2records
- `d2player.GetAllPlayerStates` is now a method of the `PlayerStateFactory`
* Removed DkillDesc and Skills singletons from d2datadict
- removed loader calls from d2app
- diablo2stats.Stat instances are given a reference to the factory for doing record lookups
* update the stats test to use mock a asset manager and stat factory
* fixed diablo2stats tests and diablo2item tests
* removed CompCodes singleton from d2datadict
* remove cubemain singleton from d2datadict
* removed DifficultyLevels singleton from d2datadict
* removed ElemTypes singleton from d2datadict
* removed events.go loader from d2datadict (was unused)
* removed Gems singleton from d2datadict
* removed Hireling and Inventory singletons from d2datadict
* removed MagicPrefix and MagicSuffix singletons from d2datadict
* removed ItemRatios singleton from d2datadict
* removed Missiles singleton from d2datadict
* removed MonModes singleton
* Removed all monster and npc singletons from d2datadict
- MapStamp instances now get a reference to their factory for doing record lookups
* removed SoundEntry and SoundEnviron singletons from d2datadict
* added highlight to animated entity
* moving provider functions for item, missile, npc, player into package export file d2mapentity.go
* changed `Create` to `New` in map entity provider functions
* add item highlight on hover
* add Name method to item entity
* entity debug rendering, with command
needed to add getter method to MapEntity interface, so that's the reasoning for changing objects/npcs/player/etc
this currently brings allocs/s up to 10 (you can check by running `fps` command, se we need to look into d2debugutils and how it handles drawing text
* reverting velocity copy, broke the map entity tests. debug display wont show velocity currently.
* adding velocity debug
* Unnecessary constructor assignments removed.
* Position implemented in d2common.Path
* Position implemented in mapEntity.Step.
* Position implemented in d2common.PathTile.
* Initial test and benchmark for mapEntity.Step().
* Removed `&& !m.hasPath()` from mapEntity.atTarget
* Direction is now updated when the path node changes mid-step and target is updated when path is set.
* Test improvements.
* Deleted old benchmark function and tidying.
* d2math.Abs added.
* Abs benchmark and optimisation.
* Negate and Distance benchmark.
* Length and SetLength benchmark.
* Lerp and Dot benchmark.
* Cross and Normalize benchmark.
* Angle and SignedAngle benchmark.
* Trivial change to Vector.Abs()
* Fixed NaN on normalize 0 vector.
* Tentative implementation in getStepLength.
* mapEntity.TileX/Y removed.
* Fixed Position and Target not being initialised in createMapEntity.
* mapEntity.Position is no longer embedded.
* mapEntity.LocationX/Y no longer used outside map_entity.go.
* mapEntity.subCellX/Y removed.
* mapEntity.LocationX/Y removed.
* mapEntity.OffsetX/Y and TargetX/Y removed.
* Direction method added to Vector, returns 0-64 direction.
* Moved Vector.Direction() to Position.DirectionTo and refactored.
* Renamed RenderOffset from SubCell and tested IsZero.
* d2math.WrapInt added for use with directions.
* Tidied up position and tests.
* Refactored d2common.AdjustWithRemainder into d2mapEntity.
* Tidying up d2mapEntity.
