feat(examples): show example queries

This introduces a new section with example
queries. Example queries not only make the
site more useful to new comers. They also
aid with SEO as they provide more content
with links to be crawled.

Fixes #44
fix(style.css): killed ancient dead file
fix(package.json): remove nested package.json

We used to have a seperate package.json
for the server subfolder which makes sense
in a way. However, it's not directly supported
by heroku to have multiple package.json
as they essentially treat it as one project.

It doesn't feel nice to have client and server
so tightly mixed but it's better to accept it
for now.

Fixes #7
feat(build): improve build process

Until now we nearly had no build process
at all. With this commit we at least
have file concatenation and minification.
On heroku, it will automatically pick
the minified file.

We don't have watch yet, so one has
to run:

`grunt && node server/web.js`

to create a build and kick off the server.
