* Improve run/walk/neutral animation handling. Initial parsing of LevelDetail records. Support for holding mouse buttons.
- Run/walk/neutral positions now map to a different animation mode(and speed) depending if in or out of town.
- Run/walk toggle which can be activated/deactivated with R key.
- Temporary(and incorrect) loading and mapping for LevelDetails records.
- Zone change label which shows the level name from LevelDetailsRecord when the player enters a different zone.
- Allow holding mouse left/right button to repeatedly generate an action.
* Remove duplicate load of LevelDetails. Replace numbers in zone change logic with their corresponding RegionIdType
* Move zone change check at the correct place
