Unable to used the PSTR() macro

[GoogleCodeExporter]

The WebServer provides the very handy method printP to print a string stored in 
program space.

So, one basically expect that you can write:

  server.printP (PSTR("Hello World !")) ;
  /* the PSTR macro is defined in avr/pgmspace.h */

Unfortunately, you can't because the parameter for printP is of type 
prog_uchar*, whereas the PSTR macro builds a prog_char*.

The fix is very simple, I just replaced all occurrences of prog_uchar by 
prog_char in WebServer.h and now I can use the PSTR macro.

Ah, we're using a different macro for the same thing in the webduino examples.

The better fix is adding a second .printP method that takes the other kind of 
parameter and calls the first version with a cast.  Since it's inlined, there's 
no overhead.
