Consider adding link to jmustache as alternative java implementation

[posto]

As a Java developer, it would be helpful to know that there are other java Mustache implementations (with their own merits).

There's a pending/impending redesign to make the list of implementations more useful, but for now it's limited to one per language. People have been adding additional implementations here: https://github.com/defunkt/mustache/wiki/Other-Mustache-implementations

In the interim, it might make sense to add "and more!" to the end of the list of implementations on the homepage and link that list?

Sure! As I just found the 3rd java mustache implementation on the wiki, I think it would be beneficial to everybody to make the list more visible.

I'm closing this since the site redesign should have all the implementations listed in the wiki page. Thanks for letting us know about jmustache.
