Added support for TP-Link v2 header firmware (TD-W8968v1)

[GoogleCodeExporter]

Hello 

I've just finished modyfing tpl-tool tool to add support TP-Link v2 header with 
MD5 checksum update/checking. Now this tool has two versions support. 

Succesfuly tested on my TD-W8968v1 router.

After modyfing "status.htm" file from the "web" directory I just need to edit 
by hand file "config.log" to change HEADER_TYPE to 'tp-link' and save it (now 
I'm working to update binwalk to set this variable automaticaly for v2 
versions).

Is anyone ever going to implement this? I tried to get the patch but seems i am 
too late, the link is dead.

does anyone have this patch, I need it for the w8980 and w9980

link to w8980 http://pastebin.com/E1VZAX4z

link to w9980 http://pastebin.com/4jB9Zcfm

w9980 has vdsl enable in stock firmware, w8980 does not, I'm trying to get 
w9980 firmware running on the w8980 to see if the vdsl gets enabled.
