Adding support for programming with FPGALink

Steps for getting it set up.

 * Get libfpgalink dependencies
   sudo apt-get install \
      build-essential libreadline-dev libusb-1.0-0-dev python-yaml

 * Build libfpgalink
   wget -qO- http://tiny.cc/msbil | tar zxf -
   cd makestuff; ./scripts/msget.sh makestuff/common
   cd libs; ../scripts/msget.sh libfpgalink
   cd libfpgalink; make deps

 * Convert libfpgalink to python3
   wget -O - http://www.swaton.ukfsn.org/bin/2to3.tar.gz | tar zxf -
   cd examples/python
   cp fpgalink2.py fpgalink3.py
   ../../2to3/2to3 fpgalink3.py | patch fpgalink3.py

 * Set your path's correctly.

   export LD_LIBRARY_PATH=$(pwd)/libfpgalink/lin.x64/rel:$LD_LIBRARY_PATH
   export PYTHON_PATH=$(pwd)/libfpgalink/examples/python:$PYTHON_PATH
