lsh 2.1 (new formula)

New formula for lsh.
``` /opt/X11/lib/libXau.6.dylib ```. It seems to be just that one.

Theoretically, yes, it *can* work without ``` x11 ```. But every time I tried to encourage it to do so, it would go seeking ``` x11 ``` libraries in ``` /usr/include ``` any way and then throw a strop when it couldn't find them.
