Add tags for releases

[nirvdrum]

machete has had several releases on RubyGems, but none of them seem to be tagged in the repository. It'd be helpful to check out the source for each released version.

You're right, however I start tagging them from the current release(I am afraid that tagging the previous releases would require rewriting history? or unnecessary merges)

[nirvdrum]

Tagging shouldn't require rewriting history. They're basically named pointers to existing commits (unless you do an annotated tag, in which case it because a commit itself). You even need to specially push the (git push --tags). More details can generally be found here:

The only thing is it might be a bit annoying since you'd need to track down the exact SHA used for each gem release.
