Typos in installDeps.sh

[ptribble]

In installDeps.sh there are a number of minor typos:

The comment says 'Is wget installed' but the check is for curl.

Other checks tell the user the URL of the missing item. Should curl do the same? ( http://curl.haxx.se/ )

The check for 'Is node installed' errors with

echo "Please install node.js ( http://nodesjs.org )" >&2

clearly, that should be http://nodejs.org

And, 'minfified' ought to be 'minified'.
