build release binaries for new release tags

[littleskunk]

At the moment autobin is building binaries only for draft releases. We had no failed binary build for a while now. It is time to move on. I would like to add ARM binaries but they will need more than one hour to complete. If we have to release a hotfix as fast as possible we can't wait more than one hour.

Solution:
Autobin should build even for published releases. Lets start with a tiny time frame of 7 days or the last 2 release tags. We don't want to build binaries for old release tags.
This will allow us to publish the release while the ARM build server is still running.

Implemented with: f87b48a

Build binaries for the latest release tags only even if the release is already published.

Oh that was only linux. I have to do the same for OSX and windows as well :/
