Client: C_glib, C++, D, Erlang, Go, Haskell, Lua, Java/Me, JavaScript, Node, Ocaml, Perl, PHP, Python, Ruby
Patch: Jens Geyer

This closes #341

Minimal server-side implementations and TODO stubs for various languages to let "make check" succeeed.
Not contained in this patch and still TODO:
- client side implementations, i.e. calls to testBinary() and appropriate tests
- server side hex printout missing for some languages
