commit 7d5b33bead9469e72756585e4c9935bb9486f845

    Provide a jsmin Makefile target for easy use of jsmin
    
    We can't distribute jsmin.c with RT, unfortunately, because of the
    license, but we can provide a way to accept the license and do all the
    steps.  The idea is to lower the barrier for fast javascript
    minification.
