Fix and Upgrade Routing Node Amount Text Box

Made the Routing Node Amount Textbox selectable again.  Fixes WayofTime#1980

Made the Text Box only selectable if a Ghost Filter Slot has been clicked.  Prevents players from typing in a value for nothing.

Added a Right-Click function to the text box.  This will clear it, set the ghost item value back to 0 ("Everything"), and select the Text Box for a new number.
