 - FileSystem 2.0 SUPER MASTER MAJOR API CHANGE !!!
 
-	The FileSystem is know build internally like for e.q the texture-, and the meshloaders.
-	There exists a known list of ArchiveLoader, which know how to produce a Archive.
-	The Loaders and the Archive can be attached/detached on runtime.

+	There exists a known list of ArchiveLoaders, which know how to produce a Archive.
+	The Loaders and the Archives can be attached/detached on runtime.
 	
 	The FileNames are now stored as core::string<c16>. where c16 is toggled between char/wchar
 	with the #define flag _IRR_WCHAR_FILESYSTEM, to supported unicode backends (default:off)
-	I replaced all (const c8* filename) to string references.
+	Replaced most (const c8* filename) to string references.
 
 	Basically the FileSystem is divided into two regions. Native and Virtual.
 		Native means using the backend OS.

 		- Big Big Testing!!
-		- Linux Version ( minor )
-		- remove all double loader interfaces where only the filename differs
-			(IReadFile/const char *filename). This blows up the the interface
 		- many loaders use their own private filesearching
-			we should rework this
 		- there are a lot of helper function ( getAbsolutePath, getFileDir )
