Server implementation for the Adafruit CC3000 library which mimics the interface of the Arduino Ethernet library server.
Fix issue when running with Arduino and avr-gcc

With avr-gcc 4.7.2 (but curiously not with the older 4.3 version) it was necessary to add a copy constructor and assignment operator to the client class.  The default versions of these that were being generated were causing the CC3000 to become unresponsive.  Also calls to interrupt polling functions were added to fix instability found when compiled with avr-gcc 4.3.
Merge branch 'master' of https://github.com/adafruit/Adafruit_CC3000_Library into server_v1
Fix issue with tx buffer still referenced in copy constructor and assignment operator after merge.
Merge pull request #30 from tdicola/server_v1

Server implementation with similar interface to the Arduino Ethernet library server class
