grunt compass task to compile scss files.

*use `grunt watch` instead of `compass watch` command*
apache server replaced with node-connect.

* unnecessary configurations removed from vagrantfile.
* puppet-apache module removed and configuration removed from manifest file and vhost template deleted.
* grunt connect task added. dev server can be started with `grunt connect` from commandline and portal can be displayed on `localhost:8000`. it is not a secure server, only http is supported.
grunt concurrent task added.

* it helps to start both watch and connect tasks in parallel.
* default task is concurrent now. just type `grunt`.
