Adding langtool to NonGNU ELPA

would you be interested in having langtool added to NonGNU ELPA. It would allow more people to install stable releases of the package OOTB. It see that there there are a few issues with maintenance and a number of issues and pull requests that ought to be addressed. If you are OK with it, you could add me as a contributor to the GitHub project and I could try to address some of these to prepare a new release.

(add-to-list 'package-archives
             '("melpa" . "http://melpa.org/packages/") t)
