PR is ready to be merged

[michalbcz]

@vire lucky, that I am so slow :) btw change PR nam to WIP: .... (WIP as Work In Progress)

[michalbcz]

@vire and what about last unchecked item "semantic release plugin" ? I am ok with that and thank you as always. You can merge it by yourself if it's ready.

[vire]

@michalbcz I need to check out how the semantic-versioning plugin works on a non-npm project like this. We don't actually release a npm package called reality-plugin but the semantic-versioning is designed exactly for this. But as a bonus it makes use of the https://github.com/conventional-changelog/conventional-changelog and takes care of versions.

So for now, I remove the checkbox from this PR and create a separate issue for that.

And for future WIP: label is a perfect choice ;) or 🚧 emoji

[michalbcz]

+1 for that emoji :)
