Latest version for wget and shell updates

Is there a “latest” URI for Omeka releases that I can script against? Something similar to where the directory has a predictable (i.e. un-versioned) name.

The version numbers complicate things a bit.

Related: is the GitHub master at always the current stable release?

We don't, but it's a good idea.

That zip isn't the current stable. We should probably mark out the current stable in github, too.
