Some unhandled paths in case expressions

[CharlesOkwuagwu]

I'm seeing these types of errors. I believe they can be trapped so it does not bring down the server.

Looking at the source:

elli/src/elli_http.erl

Lines 238 to 244 in 3ec3522

	case elli_tcp:send(Req#req.socket, Response) of
	ok -> ok;
	{error, Closed} when Closed =:= closed orelse Closed =:= enotconn ->
	#req{callback = {Mod, Args}} = Req,
	handle_event(Mod, client_closed, [before_response], Args),
	ok
	end.

I suggest we add a catch-all for each of the case statements, this way we trap any unforeseen errors

Other Suggestions?
