[kaffe] Request Headers for HttpURLConnection

[Dalibor Topic]

Hallo Sebastian,

thanks for the patch. I've looked over it and looks ni good. I have a 
question, though, before I can check it in.

You're using a Vector to store request properties. Why not use a map 
instead, like GNU Classpath does (see 
http://savannah.gnu.org/cgi-bin/viewcvs/classpath/classpath/java/net/URLConnection.java?rev=1.17&content-type=text/vnd.viewcvs-markup 
)?

cheers,
