Split off the Network configuration from Other peripherals in the Settings dialog and made PCap device configurable;

Overhauled the configuration files so that the global variables are now subdivided into sections;
Fixed CD-ROM MODE SENSE page 0x2A which was being incorrectly reported as not implemented, fixes among other things Rayman 1 and Spellcross: The Last Battle (both now see the CD-ROM and play CD Audio fine).
