Update Makefile
Initial Commit for FreeBSD - It works (but no package)

* Update Makefile to eliminate libgcrypt compile warnings of
  being deprecated
* Stub the pkg- files and the beginnings of a
* ports Makefile

Aside from that, building with the GUI works on FreeBSD, that has had
Gnome installed (it conveniently beings the development packages for
GTK3) and that was it :) libgcrypt, liblzma and libcurl were already
waiting.
