A simple but substantial change: uIP used the htons()/HTONS() macro functions for converting between host and network byte order. These names are the de facto standard names for this functionality because of the original BSD TCP/IP implementation. But they cause problems for uIP/Contiki: some platforms define these names themselves (Mac OS, most notably), causing compilation problems for Contiki on those platforms. This commit changes all htons to uip_htons instead. Same goes for htonl, ntohs, and ntohl. All-caps versions as well.

Up to now the root of the webserver filesystem was always the current directory. Now an optional file 'wwwroot.cfg' is read. If present its content is used as prefix in the conversion of http paths to local paths. This prefix may be a relative path as well as an absolute path. This is especially useful for the cc65-based targets as it ain't possible there to "just change into the wwwroot directory and start the webserver using its pathname".
