Gets the value that is stored in settings for key and converts it
to the enum value that it represents.
In order to use this function the type of the value must be a string
and it must be marked in the schema file as an enumerated type.
It is a programmer error to give a key that isn't contained in the
schema for settings or is not marked as an enumerated type.
If the value stored in the configuration database is not a valid
value for the enumerated type then this function will return the
default value.
Since 2.26
