[TASK] Restructure tests/ folder.

Move unit tests to tests/unit/. Get the old still working UnitTests
into a working state again.
Updated composer.json with required-dev packages.
Create a new folder tests/acceptance for Behat functional/acceptance
testing. Add a first Feature draft of a Behat functional test for
local login.

+The folder tests/ contains resources for automated testing tools.
+
+Here you will find PHPUnit, Behat, etc. files to test the functionaly
+of Hubzilla. Right now it only contains some basic tests to see if feasable
+this can help improve the project.
+
+# Contents
+
+* unit/           PHPUnit tests
+These are unit tests to check the smallest parts, like single functions.
+It uses the tool PHPUnit https://phpunit.de/
+
+* acceptance/     functional/acceptance testing
+These are behavioral or so called functional/acceptance testing. They
+are used to test business logic. They are written in Gherkin and use
+the tool Behat http://behat.org/
+
+# How to use?
+You need the dev tools which are defined in the composer.json in the
+require-dev configuration.
+Run ```composer install``` without --no-dev to install these tools.
+
+To run unit tests run ```vendor/bin/phpunit tests/unit/```
+
+To run acceptance tests run ```vendor/bin/behat --config tests/acceptance/behat.yml```
