graphics test first setup
Update README.md
Lot of changes, most of them to add a stress test environment, but also some bug fixes apparantly

To be honest, I made these changes before my 4 week leave, so I am not entirely sure anymore. A
quick inspection didn't show any really strange things. I think.

NOT TESTED however!
Merge remote branch 'origin/nosql' into views

Conflicts:
	tests/dbtests_data/basicDataset.json
Fixed several tests and 1 bug
Merge remote branch 'origin/nosql' into views
Fixed the stress environment: too much files were owned by user1
Fixed the way a MongoDB connection is set up
some graphic changes
graphic clickable header added
Fixed a bug where the test environment isn't always set up correctly
End requests that contain an 'Origin' header to disallow CORS
Fixed a bug where the client still used the old API of js-webdav-client
resolved some test bugs
Added an (PHP) API for POST authentication codes.

The HTTP API is not added yet. Therefore I also didn't include the check anywhere.
The goal of the POST authentication code is to prevent attacks where a different
website submits a (hidden) POST form to change settings of a user.
Fixed a bug for clients that use the 'Origin' header while on our own domain
Merge branch 'master' of github.com:sara-nl/BeeHub
Added the HTTP API to get the POST authentication code
Fixed BeeHub::startSession() so that it won't attempt to start a session when run from cli

This situation occurs during tests for example!
Added checks for the POST authentication code
