A bunch of (smaller) changes…

First of all, thank you for the work you’ve done. :thumbsup:

I’ve made some changes I’d love you to look at. Either select them all, do some cherry-picking or deny the pull requests – it’s up to you.

**What did I do?**
I basically didn’t change that much – I’d rather say I “optimized” here and there. I removed unnecessary files, optimized the Hamburger SVG, replaced the Favicon with a real ICO file, etc. Just have a look at the commits.

:wave:

this was already done earlier
