Ethernet & String clash

Hi there,

i got problem with String & ethernet library togheter, because in Ethernet library there are also the String library, so i can't declare also in my schetch.

my personal fixup is to move away (no_complile subdir of hardware/libraries/Ethernet directory), and have the declaration on top of my schecth.

please note to include Wstring.h before Ethernet.h

#include <WString.h>
#include <Ethernet.h>

Please advice me if that workaround is fair good or i'll got problem later.

thanks in advance
