Fixed a few issues in VendorComponent.
- Corrected serialization to only happen on construction.
- Added functionality to refresh the vendor based on info from the vendor component table
- some whitespaceing inconsistencies.
- Sorted includes.
Tested the vendor in Nimbus Station and when the player re-enters the world, the vendor inventory refreshes, as opposed to previously where the world would need to reset in order to refresh the inventory.
