There can be empty tracks, ignore them.
	* FileSystemIDandChk/Plugins/FAT.cs:
	  Modified logic to work around FAT12 predating DOS 2.0.
	  Limiting it to disks supported by 86-DOS and DOS 1.x, yet
	  probably it will give false positives.

	* FileSystemIDandChk/PrintHex.cs:
	* FileSystemIDandChk/FileSystemIDandChk.csproj:
	  Added function to print hexadecimal output of sector, useful
	  for debugging with compressed disk images.
	* FileSystemIDandChk/ImagePlugins/CDRWin.cs:
	* FileSystemIDandChk/ImagePlugins/DiskCopy42.cs:
	  No need to call them "handler"s.

	* FileSystemIDandChk/Main.cs:
	  DEBUG lines should only appear while on debug mode

	* FileSystemIDandChk/PartPlugins/MBR.cs:
	  Do not check MBR presence on less than 512 bytes/sector
	  disks

	* FileSystemIDandChk/Plugins/FAT.cs:
	  Get cleaner output, add newline.

	* FileSystemIDandChk/Plugins/ODS.cs:
	  Do not check FILES-11 (ODS) presence on less than 512
	  bytes/sector disks
