1.0.12 -> 1.0.13

	* Added server discovery protocol into implementation and
	  protocol documentation.

	* Missing packet numbers added to the protocol documentation.

	* Short explanation about the IP specific use of the protocol
	  into protocol documentation.

	* Made a generic packet encode/decode routines.  Most of the code
	  uses those routines now and all the new code should use those
	  instead of encoding and decoding the packets by hand.
	
1.0.11 -> 1.0.12

	* Command line parameter -r - means that no actual media root
	  directory is defined.  Only directories mounted with -S flag
	  appear in the root directory, which is entirely virtual and
	  doesn't correspond with any real directory.

	* Command line parameter -L that loosens the security awareness
	  of the ccxstream server so that symbolic links are followed.
