added a script to update the xilinx builder

Copies over a xilinx build

It would be great to implement a version that pulls from github but that
will have to wait
Added License
Fixed some mistakes associated with defines
Added a new script to generate a project config

Now the configuration of the output project will be customized to the
correct board
Added configuration flags for dionysus

Now the build tool will automatically build a Binary which is the format
required to upload to Dionysus
Added two functions for fixing paths
Changed the default output paths

This is changed so when I am debugging the design I can find the results
in the specified 'project' directory
Commented out a debug print statement
updated the xilinx_builder dir

Now it only contains the essential files for building an FPGA image
implimented the xilinx builder

Now as apposed to using the old tcl version of the build, the image
builder output will use the new xilinx_builder, much cleaner!
