Get feature file from /features/

Quick read of the feature file from the harddrive. Will
change in future to use features files from other locations.
Add Mink to Behat

Allows the second step of the feature to pass.
Make feature display on the page
Fix make contents of feature more readble

Simply convert new lines to br for now.
Add colour checking scenario
Add GherkinViewer namespace
Refactor how stories are displayed

The first idea was stupid. This is a much neater approach
to displaying/rendering stories with bootstrap inside
a browser.
Use latest version of behat

Wanted to use version 3 of behat for some of the extra features
and to experiment.
Make tests pass
Revert to older version of behat
