March Release: 0.5.0

Hi,

Heads-up: I plan to do the release later today, in ~5-6 hours. So if there are PRs that you want to be included, there is still some time.

[original thread by Marc Dumais]

I updated the changelog for today’s release here if anyone has comments :slight_smile: https://github.com/theia-ide/theia/pull/4751

The release is delayed a bit; looks like Travis is not working ATM. I will check back a little later

ok, I’m going to try now. Please do not merge anything until I am done

ok, all done

Thanks @vince-fugnitto for the CHANGELOG and all contributors who worked on the content of this release.
