Vagrant ize

Now Skyperious has a Vagrantfile so that it is possible to run it in a local VM, in a couple of commands.
No more hassles installing its dependencies.

Steps for using the Vagrantfile:

1. `vagrant up`
2. A VirtuaBox window will appear
3. Wait until `vagrant up` finishes setting up the VM
4. Log into the console as the user 'vagrant', password 'vagrant'
5. Run `startx -- :1`
6. Now you are in ubuntu desktop env
7. Open a terminal
8. `cd /vagrant`
9. ./skyperious.sh &`
10. et voilà
