* Added BDiskSystem::ShortName() and everything needed to get it there.

* Added BDiskDeviceRoster::GetDiskSystem() method, that can get a disk system
  by short/pretty/module name - since they should all be unique, I put them
  in a single namespace, please complain if you don't like that :-)
* Cleaned up DiskSystem.h and DiskDeviceRoster.h according to the updated
  header guidelines.
* Renamed ntfs pretty name from "ntfs File System" to "Windows NT File System".
