Tuna 0.3.0[beta] released, still looking for feedback

[curt <curt@...>]

0.3.0 is up, this release has been re-factored to make the C api 
completely asynchronous. Also ran some memory benchmarks, seems the 
overhead for a task (including its stack and own lua_State) is around 
7k, so yay for task-per-entity stuff, since it consumes 0% cpu while 
asleep/yielded/waiting on event.

Also some bugfixes, and API tweaks. I am still trying on messaging as I 
actually use this in a project, but any feedback is welcome. Next step 
is to make the Tuna::Message object iterable.. somehow.. don't like any 
of the ways I've tried to do that yet. Also want to make sure I outline 
how sending Nil messages works as a signal/event pattern, and optimize 
for that use case of them.
