thankyouverycool 92fffc3abc LibGUI: Rename CallOnChange => AllowCallback and implement elsewhere
This is a helpful option to prevent unwanted side effects, distinguish
between user and programmatic input, etc. Sliders and SpinBoxes were
implementing it idiosyncratically, so let's generalize the API and
give Buttons and TextEditors the same ability.
