Unity Dialogue System - Removing whitespaces, special characters and making errors case insensitive

In this video we're going to be removing whitespaces and special characters from the nodes, groups and toolbar text fields and also make so our node and group errors are case insensitive.

This means that we can't write names such as "Dialogue Name" or "Dialogue&Name", as they will be transformed into files, but also means "dialogueName" and "DialogueName" will now be considered the same in our error system.
