INI settings for the MATHS filters are not read back correctly. This is because a Replicator is used to intuitively multiply a number of grouped settings, but the Replicator itself has no key, so it's not being asked to create the necessary panels. I'm not sure yet how to generalize this the best and most robust. It could be viewed as a flaw in the XML but INIshell should be able to do this.

Implemented within commit de0b8d4e3a7. An empty Replicator key now triggers a different method to check if it can spawn the requested key (namely, it goes looking for it in the corresponding XML node). Used in this way, a Replicator is more of a GUI element because it does not correspond to any INI structure but is used for UI purposes (like a frame, but interactive).
