Ported the Roland MT-32 emulation (using MUNT) from bit's MT32 emulation branch of PCem; Sanitized the OpenAL give buffer code in openal.c a bit; NVR path is now specifiable in the Settings dialog; Added Logitech 3-button serial mouse per protocol description by waltje; The RTL8029AS and the BT-958D now actually use the PCI IRQ routing; Fixed BT-958D PCI device initialization on the bus; PCI IRQ routing now respects the edge/level setting set on ports 4D0/4D1.
