- [X] Adds `Respawn` command
- [X] Adds `EditSpawner` command
- Usage: `[global editspawner <type> <arguments> set <properties>`
- This command replaces the arguments (optional) and properties of the affected spawners for that type
- [X] Adds `SpawnProps` command
- Usage: `[area spawnprops`
- This command brings up a gump to modify targeted spawners based on the targeted entity.
- To do this, the props/values are copied and then used to construct a properties list for the spawner entry.
Closes#531
