[instructions] jshint-emacs-conf changed name

[ericprud]

The Usage section immediately follows the git clone instructions, presumably leaving the user in the directory into which git created the jshint-mode directory. The instructions are

$jshint-emacs-conf >> ~/.emacs

The current conf script appears to be named jshint-emacs.js; I think the following instructions would make it trivial for newbies:

• before pre section add ", (presuming you are in the directory where git created the jshint-mode directory)"
• change the instruction to $ ./jshint-mode/jshint-emacs.js >> ~/.emacs
