Title: Fix lots of things

This commit:

- exports the module
- binds the function where `this` is used and was undefined
- fixes the ordering of messages so that they are always delivered in a FIFO fashion, since the module is called `then-queue`
- adds a `length` property, which lets you see whether there are messages waiting, or receivers waiting.
