Hi PKP team, can someone please review and merge this PR.
Thank you

I don't understand why md5sum check is failing. No change was made to the file since the previous commit when it succeeded. I've checked the md5sum of the file again and it appears to match the expected. @bozana do you know how to re-run the checks?

Hi @Alex-nz, it looks like the tests are passing now, and I've checked the md5s manually as well - sometimes the tests can have issues when there are multiple releases in a single PR. @asmecher ready for your review!

@Alex-nz, I had merged this, but ended up reverting it -- it looks like you're re-using the same version numbers for new releases. For example, there's already a 1.3.3.0 release in the Plugin Gallery. This makes it hard to debug, and will probably cause problems with changing URLs and checksums. I'd suggest bumping the build number and re-submitting this with new version numbers that haven't been used before.

Hi @asmecher, I think this is a fully new plugin, that does not exist in the plugin gallery yet...

[asmecher]

@Alex-nz and @bozana, ah, my mistake! I misread this as a new revision of the plugin above it in the Plugin Gallery. I've re-added the commits.

Thanks @asmecher and @bozana . That's right, this is a completely new plugin, it just follows the same version number convention as the other one from us.
