* FileSystemIDandChk/Plugins/ISO9660.cs:

Added code preventing it to be run on each partition,
	  because this filesystem will be once and only. Now it runs
	  only one time whenever there are partitions or how many.

	* FileSystemIDandChk/Plugins/FAT.cs:
	  Added code to handle false positives (FATs can be 1 or 2,
	  maybe 0 in the wild, never bigger).
	Modified for BinaryReader class.

	* FileSystemIDandChk/Plugins/BFS.cs:
	  Missed negation operand

	* FileSystemIDandChk/PartPlugins/NeXT.cs:
	* FileSystemIDandChk/PartPlugins/AppleMap.cs:
	  Added constants and modified for EndianAwareBinaryReader
	  class.
