Plugin tags

Hey,

I noticed your plugin stopped tagging releases in subversion, making it impossible to use in a version-controlled environment (like with composer).

See the versions available on wpackagist.org, for instance: https://wpackagist.org/search?q=flow-flow-social-streams&type=any&search=

See the docs for learning how to do it: https://developer.www.ads-software.com/plugins/wordpress-org/how-to-use-subversion/#tagging-new-versions

Would it be possible for you to look into that? Thanks!
