Bookstack: Google ReCaptcha Configuration

[dfirence]

Hello Team

Does anyone have a solid tutorial to implement Google ReCaptcha v2 for :

1. Login Form
2. Registration Form

I would like secure Bookstack a bit more

This, or some other spam prevention system like it, is critical for installations which are publicly accessible. We are getting tens of spam sign ups per week, which take a lot of management time to check and remove. Thanks.

I still need to decide if this is something I'd support in core or if I'd prefer to just provide extensibility for, But if you're urgent for something I've pushed a crude example implementation at this commit:
https://github.com/BookStackApp/BookStack/commit/c49454da2833eb31b426e6b6ecfd790fad58567b (Patch)

Tested with reCaptcha v2.
Is taken from the current stable codebase so patch could be applied to a release BookStack instance, You just need to change the two keys (Shown surrounded by %%, Replace % signs also).
