- Added ability to configure axis min, centre and max values in INI file. This allows some types of steering wheel pedals that use an inverted value range to work properly with the emulator. - Modified CINIFile to read and write signed numbers (needed for above change). - Added check at configuration start for "bad" input sources such as axes that are wrongly calibrated or buttons that are always triggering a value. Otherwise they cause the configuration loop to wait indefinitely for the axis or button to be released. - Removed superfluous check for XInput devices when XInput is not enabled in CDirectInputSystem. - Improved force beedback code in CDirectInputSystem and also added the extra feedback effects needed so far for drive board emulation.
