Andrew Smith 31a2ac94c7 LibGUI: Fix crash in GML Playground auto-completing SpinBox props ...

Crash was caused by deferred invocation of a lambda on the SpinBox's
TextEditor widget's on_change. The lambda referenced the SpinBox ptr,
but in GML Playground the SpinBox was free'd before the deferred
lambda could run, causing a use-after-free error. Fixed by using
a weak ptr to detect if the SpinBox was free'd.
