Installs an action called @action_name on @widget_class and
binds its state to the value of the @property_name property.
This function will perform a few santity checks on the property selected
via @property_name. Namely, the property must exist, must be readable,
writable and must not be construct-only. There are also restrictions
on the type of the given property, it must be boolean, int, unsigned int,
double or string. If any of these conditions are not met, a critical
warning will be printed and no action will be added.
The state type of the action matches the property type.
If the property is boolean, the action will have no parameter and
toggle the property value. Otherwise, the action will have a parameter
of the same type as the property.
