A brand new update display

We change the output format of the updates, you can read more about that in #350 and #354.

Reduce the number of dependencies

We no longer need the libssl runtime dependency which, as you probably already know, is one of the hardest dependency to install...

Make the engine accept updates asyncly

Now you will be able to send updates to the HTTP server without having to wait for it to process anything but the body parsing (#340).

The big breaking release

This is the first big release of MeiliSearch and it breaks many HTTP APIs but don't worry the documentation is up to date.
