Started adding Flask app

- Added deps in requirments.txt and created requirments_dev.txt
  requrierments_dev.txt is now used by vagrant. This allows us to use
  packages that will not be needed in a production env. in the dev. env.
- Hello World Flask app created.
- Looking at BDD dev with Behave and Selenium
- Added Twitter Bootstrap and a template
- Changed the provision structire quite a bit to try
  and separate each logical part into its own playbook
- Added some provision steps for the web-part
Tidied things up, some symbolic links between web-part and original part
- Got BDD development using Behave up and running. To runt integration-tests, run `behave` in the `~/app/www` dir.
- Some general structuring of the webapp. Something resembling a MVC framework is now up and running.
- Started on static routing.
Tidied up provision again and added the new requirment structure.
Merge branch 'flask' into develop

Added the flask branch and modified a few dependencies that was left over from testing. Running `vagrant provision` should install everything that is needed.
