Add git tags to released versions

[laumann]

It'd be nice if tags were created for each released version, to make the specific commits easier to find.

Thanks @laumann 👍 Sorry I forgot to tag the latest RC release!

I've added a tagged release for 0.5.0-rc.2

[laumann]

Nice, I was looking for older versions, both for the 0.3.x and 0.4.x - would you add tags for those as well?

[laumann]

I'm liking the detailed release notes, it's good 👍

[KodrAus]

@laumann No problem, when I find a little downtime, I'll go through and add tags for the previous releases 👍

I went through the commit history and pinned all versions down to the right commit from back then. Not gonna lie,. I hope I didn't fuck up stuff :) 😱
