* Added: the *SetSettingsNotice()* method which can be used instead of the *AddSettingsError()* method. The new method does not require an ID to be passed.
* Changed: **(Breaking Change)** the parameters of *SetFieldErrors()* method; the first parameter is now the error array and the second parameter is the ID and it is optional.
* Changed: that when multiple labels were set for the field types that supports multiple labels but the *name* key was set null, it now returns the default value instead of an empty string.
* Tweaked: the settings registration process including sections and fields to be skipped if the loading page is not one of the pages added by the user.
