Solved issue in rsync_project and implemented downstream synchronization

[apbarrero]

When parsing for rsync address, the variable being parsed was 'env.host' instead of local 'host' which holds the actual value to be used.

Downstream synchronization option implemented.

Why did you mix up a bugfix and a feature in the same PR? 😢 (link)

I'll cherry pick the bugfix part for now; the feature itself looks OK but I need to test it & it needs a changelog entry too.

[apbarrero]

Sorry for the mixing up. Disclaimer: first PR. Thanks for the reference link.

About the feature, I got it working in my environment but had problems to run tests locally, so I couldn't debug so far. Still working on it.

@apbarrero No worries, that's why I added the link ;)

Please do make a new PR once you have the inverse-rsync stuff documented/tested/whatever. (Testing this part of things isn't 100% required right now, since it requires external programs/systems, but recording results of manual tests in-ticket would be awesome.)

Thanks!

[apbarrero]

New PR done. I filed a new issue before, so to get a number to reference in the changelog. Then I noticed the PR created a new issue itself. I'm kind of confused on how to proceed in this case :/

Thank you for maintaining this great tool!

Yea, "Issues" and "Pull Requests" are muddled together unfortunately, PRs are effectively just a special case of Issue, are given Issue numbers and so forth. I closed the "extra" ticket so only the real PR is left now. Will poke at it momentarily, thanks!
