* DiscImageChef.Helpers/BigEndianStructure.cs:

* DiscImageChef.Helpers/DiscImageChef.Helpers.csproj:
	  Added code that directly marshals from a big-endian byte
	  array. But untested with nested structures.

	* DiscImageChef.Partitions/Acorn.cs:
	  Added support for Acorn FileCore partition, closes #4.

	* DiscImageChef.Partitions/BSD.cs:
	  Moved BSD partitions from inside MBR code to separate code,
	  as they can (and do) appear on other architectures as the
	  only scheme.

	* DiscImageChef.Partitions/DEC.cs:
	  Added support for DEC disklabels, closes #11.

	* DiscImageChef.Partitions/DragonFlyBSD.cs:
	  Added support for DragonFly BSD 64-bit disklabels.

	* DiscImageChef.Partitions/PC98.cs:
	  Added support for NEC PC-9800 partitions.

	* DiscImageChef.Partitions/RioKarma.cs:
	  Added support for Rio Karma partitions.

	* DiscImageChef.Partitions/SGI.cs:
	  Added support for SGI DVHs, closes #9.

	* DiscImageChef.Partitions/UNIX.cs:
	  Moved UNIX partitions from inside MBR code to separate code,
	  as they can (and do) appear on other architectures as the
	  only scheme.

	* TODO:
	* README.md:

	* DiscImageChef.Partitions/GPT.cs:
	  Added new partition type UUIDs.

	* DiscImageChef.Partitions/MBR.cs:
	  Moved BSD partitions from inside MBR code to separate code,
	  as they can (and do) appear on other architectures as the
	  only scheme.
	Moved UNIX partitions from inside MBR code to separate code,
	  as they can (and do) appear on other architectures as the
	  only scheme.

	* DiscImageChef.Partitions/Sun.cs:
	  Added new partition types.
	Prepare structures for marshaling.
