Script Editor: Escape loses changes

[AwooOOoo]

Describe the bug
When you press ESC it backs out of the editor window without asking you to save changes like when you press the new button and have made changes. (I learnt this the hard way =/).

To Reproduce
Steps to reproduce the behavior:

1. Create a new script and add some stuff
2. press escape and you are returned to the main screen
3. changes are lost

Expected behavior
When editing a script and you press ESC it should ask you if you want to save the changes (just like when you press new).
