* FileSystemIDandChk/Plugins/ODS.cs:

Browse Source 
Use StringHandlers class to prevent garbage coming from
	  strings (even if they are not C strings, it does not hurt).

	* FileSystemIDandChk/Plugins/AppleHFS.cs:
	  Use constants.

	* FileSystemIDandChk/Plugins/BFS.cs:
	* FileSystemIDandChk/Plugins/AppleMFS.cs:
	* FileSystemIDandChk/Plugins/AppleHFSPlus.cs:
	  Use constants and EndianAwareBinaryReader class.

	* FileSystemIDandChk/Plugins/Opera.cs:
	  Use a superblock structure and EndianAwareBinaryReader
	  class, reduces lots of code.
