Feature/add support for bds

[fdp1nm]

Hey Karim,

Here are the modifications needed to make it work on my BDS.

• I added the user agent header name, which was there in the AVRdevice but was ommited in the BDS
• I moved the CRLF marking the headers end in the request. The prepending CRLF was not supported on my BDS, and ther has to be a double CRLF between the last header and the payload. This modification also helps debug with wireshark, as it then decode the request as an HTTP POST, so it's easier to read.

I also checked the required changes in the headers between the AVR and the BDS version. The only difference that maters is the HK_APP insted of the AVR. But keeping the same User-Aent as your would make no difference.

Thanks a lot for your help.

Nicolas

Thanks for your work! I'll test these changes on my AVR. If it still works, I'll merge it with the master branch. I'm not sure if this will work, since my AVR won't accept "correct" HTTP requests. I'll keep you posted.
