Update GettingStartedPage.js

Add additional requirements to actually use IE8

* console shim, because the IE8 console only exists while the console is open.
* html5shiv & html5shiv-printshiv because newer html5 elements don't work without it

Update GettingStartedPage.js
Rename "navOpen" to "navExpanded"

There seems to be a non-working mix navOpen and navExpanded which means
getInitialState() sets navExpanded in the state, but isNavOpen refers to
the uninitialised navOpen. I have made it all use navExpanded, which
appears to be the intention, and also added some sensible defaults to
make it easier to get right.
