Update the serverless-offline startup hook

[darthtrevino]

I'm having trouble with the serverless-offline startup hooks in the latest version of serverless-offilne. It seems like you have to bind to the offline:start:init event in order to have things boot properly into the serverless-offline cycle.

When will this get merged? Seems pretty important.

Any update?

@darthtrevino Is this still an issue? We're using the master branch since quite a long time (which does not have the changes), but using serverless-offline works quite well.

I think @Whoaa512 just got it working too, without this PR.

[Whoaa512]

As long as you have both plugins in your serverless.yml (with offline as the last plugin) and you run the command sls offline both plugins should work properly.

The implementation in #131 is more complete and also keeps the start hook too. I will close this one in favor of #131. Can you please test with that?

[HyperBrain]

I tested #131 also for incompatibilities when using offline without the start argument. Works. So I'll close this one in favor of #131 as it is more complete.
