order behat tests to reflect functionality

[Rebecca Blundell]

The behat test names and the folders they are organised in don't reflect the functionality of the tests. Reordering the tests by functionality may make them easier to find and consequently easier to maintain.
I suggest ordering tests into the following folders:
- security
   -for security tests
- settings
   -for tests that check site settings
- site_content
   -for tests that check site content is correctly displayed and can be interacted with
- site_features
   -for tests that explore whether site functionality works
- social
   -for tests related to interaction with others: comments, groups, messages, friends, submissions...
- user_content
   -for tests related to content

This commit moves all the test feature files into new folders, hopefully

you think the new order makes sense.
