[Feature request] Hotkey for closing script popup

[nish7x]

Can we have an Escape key to close this? It would act just like clicking the X button, so if content is not explicitly saved, it'll be discarded. For this you could have a popup stating Changes not saved [Save] [Discard changes] if you please, or not.

Alternatively, you can also make it close if clicked outside the popup area. This makes it easier since Client Script button to open is on the extreme left, and close button is on the extreme right. Would reduce the cursor movement.
