+DEPRECATED
+SYNOPSIS
+ int prevent_insert()

+ rooms if you want to prevent to put something into current
+ object.
+
+ Return true if ok, otherwise 0. That means that default is
+ that it is not possible to put something into an object.
+
+HISTORY
+ Deprecated in LDMud 3.3 as transfer() has been deprecated.
