### Summary
Modifying a ValueLinkList using one of the methods will bump the "version". This field is used by iterators (foreach loops) to determine if the link list was modified while iterating. The sector.Items (and in the future other lists), will no longer be safe to modify while iterating. The server will _CRASH_ if the ValueLinkList is modified.
Thanks to @stefanomerotta for help!

### Summary
Eliminates `IPooledEnumerable<T>` and `eable.Free()` from `Map` for items. This drastically simplifies code that iterates in range, for example:
```cs
foreach (var item in m.GetItemsInRange(5))
{
}
```
The code above no longer requires an eable and calling `Free()`.

This update changes the default RunUO SpawnerGump's overall look and feel and expands slightly some functionality. Inspired by the XmlSpawner gump.


1. The name of the spawner is displayed
2. This displays the total current spawn with the current allowed max spawn
3. Cleans up the display of the current count and the max count
4. The ability to turn on/off the spawner
5. Several changes to buttons
- Simple Save and Cancel instead of Okay, Cancel and Apply.
- Props button to display spawner properties
- Goto button to teleport to the spawner
- Reset button that will clear all the spawned mobs and turn off the spawner
- Repositioned the buttons to make a little more sense
6. The sum of all the max spawn values per entry, from all pages
* Makes EnsureDirectory properly work for relative and absolute paths
* Adds a `PathUtility.GetFullPath` which returns full paths for relative paths to `Core.BaseDirectory`. If the path is absolute, it will return as-is.
* Moves EnsureDirectory to `PathUtility`. So `ScriptsHandler.EnsureDirectory` and `AssemblyHandler.EnsureDirectory` are now `PathUtility.EnsureDirectory`
* Fixes crash guard so that it copies accounts properly.
* Changes world save and auto archive to use a random folder name inside of the temp folder.
