Speed up Webserver demo data rate by not sending a full ethernet frame each time, preventing the receiver from using a delayed ACK scheme which slows down the connection. TELNET server cleanup.

Move DHCP negotiation timer into the DHCP connection application state structure, so that each connection gets its own timeout counter (only one connection currently used, but this way is more correct). Add const correctness to static data in the TELNETServerApp.c and HTTPServerApp.c files.

Fix DHCPClient init code in the Webserver project writing to the incorrect application state location (thanks to Mike Alexander).

Make Webserver allow HTTP requests for files with up to 50 characters in the path instead of 30, to be in synch with the project documentation.

Change Webserver project's ENABLE_DHCP compile time option to ENABLE_DHCP_CLIENT to more accurately indicate its function.

Exclude FATFs from the Webserver project documentation. Rename the functions in the HTTPServerApp.c/.h files so that they use the correct "HTTPServerApp_" prefix, and not "Webserver_".

Replace the Webserver demo's uIP with the latest code ripped from the Contiki project by Adam Dunkels.
