[Feature] Update rename dialog to be more usable

[Gear61]

This is only applicable when you have more than 1 instance of a name.

1. Prefill the "# of copies" EditText field with the current number of names.
2. Add an "All of them" button to the dialog that fills the EditText with the current number of names. You can use the neutralText() and onNeutral() callbacks to do this.
3. Change the copy to "How many copies of "X" do you want to change? You currently have Y copies of this name." where X is the current name and Y is the current amount.
