Update Write-Menu.ps1

[justinainsworth]

Made a couple of improvements.

1. Added the ability to display any property of an object sent, so it doesn't have to be named name. Controlled with the Name Parameter. It defaults to name, so it is not a breaking change.
2. Added the ability to return the entire object, and not just the name. Helpful if there are objects with the same name. This is also configurable with the ReturnProperty parameter, with the default behavior being the same as before.
3. Moved a lot of the configuration variables into a single private object.
4. Added a cleanup function to ensure the cursor returns to normal, and the window title returns to the initial value.
