Slackin-extended

[emedvedev]

Hi,

I've noticed there's a bunch of unmerged pull requests that were useful to me, as well as some features I didn't see implemented, so I took the liberty of forking the repo and adding some features that I found useful for my case.

Among the new features:

• Invisible reCAPTCHA support
• Google Analytics support
• two color schemes and configuration of the accent color
• color customization for the SVG badge
• wildcard support for e-mail restrictions

I've also merged #303, #313, #269, #332, #336, #343, #345, and #111. Here is the full change log: HISTORY.md.

There were too many changes to submit it as a PR, so please feel free to cherry-pick anything you want: emedvedev/slackin-extended. Hopefully, other people will find the modifications just as useful as I did.

On a related note, I've switched templates and stylesheets to Pug and SASS, respectively (just a personal preference, it was much easier for me to work with), so I'll understand if you don't want to pick up all the changes. :)

Lastly, thank you for the amazing project! I might have added a few features, but all the credit should really go to you.
