Whenever harddisks/disks are inserted (or removed) and *if path has changed* then:
. Then the internal save-state's path & filename will be updated to reflect the new defaults.
. LoadConfiguration(): Read the save-state pathname from Registry before harddisks/disks.
Also:
. CiderPress: only save pathname on OK.
. Refactored CPropertySheetHelper::BrowseToFile().
. Extended support for -d1,-d2,-h1, etc such that if the param is "", then it will eject/unplug the disk/harddisk.
Changes to ease code compilation in GCC.
Disk_t and HDD contain a std::string and for this reason they need a proper constructor, ZeroMemory is not guaranteed to work.
