GRAPHICS: MACGUI: Implement lockable widgets

Browse Source 
Lockable widgets are those which takes in all input
and if set then no other widget can take any input
its same as them being inactive, no buttons, animations
etc will work.

This is implemented to support `modal` property of window,
which requires a window to take all input and prevent all
others from having any actions.
