Fixed download after major changes at laracasts

Fixes #74

After laracasts recent changes, lessons and series cannot be crawled anymore because now that info is loaded via xhr requests through Algolia API. I switched the crawler with an Angolia client and updated README with new intructions.

The ALGOLIA_APP_ID and ALGOLIA_API_KEY env variables must be filled manually.

It would be nice if someone does another pr crawling them from the js files

I tested by following your instruction in your updated README.md and its working.

Great work @storrella, thanks for your effort. 💪

Since I can't test it myself, I'll wait for some more feedback before merging.

Having a little trouble getting the key and id. I get the following;

o = "x-algolia-api-key" === r || "x-algolia-application-id" === r ? "hidden for security purposes" : e[r], t[r] = o

Any recommendations for getting these?
