* DiscImageChef.Partitions/Human68k.cs:

* DiscImageChef.Partitions/DiscImageChef.Partitions.csproj:
	  Added Human68k partition table.

	* DiscImageChef.Partitions/RioKarma.cs:
	  Corrected typo.

	* DiscImageChef.DiscImages/ZZZRawImage.cs:
	  Detect X68000 SASI hard disks that use 256 bytes/sector.
	Correct size of ECMA-154 magnetoptical.

	* DiscImageChef.Partitions/PC98.cs:
	  Correct handling of partition name, do not directly marshal
	  as it may crash.
	Prevent false positives checking for sanity and partition
	  type, so this limits it to FreeBSD right now.

	* DiscImageChef.Partitions/Acorn.cs:
	  Do not try to read past device.

	* DiscImageChef.Helpers/BigEndianMarshal.cs:
	* DiscImageChef.Helpers/BigEndianStructure.cs:
	* DiscImageChef.Helpers/DiscImageChef.Helpers.csproj:
	  Reworked big endian marshal. Does not traverse nested
	  structures.

	* DiscImageChef.Partitions/SGI.cs:
	  Corrected big endian marshaling, manually traversing nested
	  structures.

	* DiscImageChef.Decoders/LisaTag.cs:
	  Removed temporal variable.

	* DiscImageChef.Partitions/Sun.cs:
	  Sun insists all devices must be 512 bytes/sector. Really.
	  Even CDs. But this allows bigger ones.
