Make the handler accept other messages than the http_request

[Arnaz87]

Currently the lua actor only accepts http_request messages, but that heavily limits it's functionality, so torchbear apps cannot schedule stuff, cannot have a repl, cannot create new actors, etc.

you're talking about the bridge?

#74 #25 I think you're using "handler" differently than how I intended, as specifically an extension of a binding that continues passing data to LuaActors during runtime.

this is the plan for: #19 #10

https://github.com/foundpatterns/torchbear/commit/b81bcc2e82d38bb0ac6b396843654eada2370b14 advanced it.

#121 is related
