<FileDescription>
	This is the File Browser Connector for ColdFusion.
	
	Notice: 
	FCKeditor needs an UTF-8 encoded XML packet. 
	Only CFMX can encode in UTF-8. If this browser doesn't work in CF 4.0/4.5/5,
	please send me a notice. We then can use an more object oriented approach (CFC)
	to clean up this code :)
	
	Please declare the base path (e.g. /UserFiles/) as an Application or Server variable
	Directory structure (with optional subdirectories built by the user). 
	The "Type" subdirectory is automatically submitted by FCKeditor:
	/UserFiles/Image/
	/UserFiles/Flash/
	/UserFiles/File/
	/UserFiles/Media/
