Updating GCE PHP Getting Started sample to v1beta14

The app.php file looks good, aside from the one comment. I have some suggestions
for the README file:

- Add a link to the php client library at this line "The google-api-php-client
library checked out locally"
- In this sentence: "Under the redirect URI, enter the location of your
JavaScript application" - was this copied from the JavaScript demo? You might
want to remove the word JavaScript to avoid confusion.
- Under the setup section, step 2, add a bullet for the $project variable.

File app.php (right):

https://codereview.appspot.com/7301093/diff/1/app.php#newcode38
app.php:38: $client->setDeveloperKey('YOUR_DEVELOPER_KEY');
Is the developer key really necessary? It's not mentioned in the README, and I
don't think it's necessary to use the API. I recommend removing this line.

LGTM!

I totally missed the project key in the README, but in any case, I think it's
good to remove it since it's not necessary.

Thanks!
