- Split the IHNM script functions into a different file

- Added two new defines, ENABLE_IHNM and ENABLE_SAGA2 (enabled by default), which can be used to remove the parts of the SAGA engine which are specific to IHNM and SAGA 2 games. Hopefully, this will reduce the size of the engine even more for platforms with little memory (e.g. the Nintendo DS)
