ft2232 support in quartus II

There's a previous thread about the Arrow/FT2232 programmer option.

The driver could be downloaded from arrow (and should be still available there), I don't see a problem to use it at least for personal purposes. The most problematic point is, that's it's considerably slower than USB Blaster particularly in debugging, as reported in the said thread.
