Added a todo to add a tag for release at any version

Good evening,

Tonight I am writing to humbly put in a request for you to tag this project.

The reason is that a lot of users want to rely on the most "stable" release, by
the most broad definition of the term. For me, it is really simple, I am setting
up a "stable" Emacs configuration of my system here https://github.com/grettke/home/blob/master/.emacs.el
and I would like to rely 100% upon MELPA Stable http://stable.melpa.org/#/ .

I've used your package for a long time, love it, and so do many, many others.
This is a way to get that project out to the other thousands and thousands of
users who also rely upon MELPA stable.

All it takes is for you to create a tag, and within hours, it will show up on
MELPA stable.

Can't wait to hear about what you think and whether or not a tag is in this
project's future!

Kind regards,

Grant Rettke

P.S.

I use your plugin on a weekly basis. It is critical. It is hugely valuable and used by MANY.

It would help greatly to get a tag out so people can pull it from melpa stable.
