Plip10359 security controlpanel fixes

[jcerjak]

This is a pull request for #216 . Most of the work was already merged previously, here it's mostly cleanup stuff:

• read security settings from the registry instead of portal properties, including removal of old properties, which are not used anymore
• fix tests, add another robot test
• changelog

There are also fixes in a number of other packages, which should be merged along with this PR, please wait with the merge until I add the list of other pull requests here.

Added a list of pull requests, which should be merged along with this one. The tests are passing on my local machine, except I'm getting u'arguments[0] is undefined' errors with some of the robot tests,, e.g.:

Failure in test Scenario type title is normalized (test_types.robot)
Traceback (most recent call last):
  File "/home/ibi/.buildout/eggs/unittest2-0.5.1-py2.7.egg/unittest2/case.py", line 340, in run
    testMethod()
  File "/home/ibi/.buildout/eggs/robotsuite-1.6.1-py2.7.egg/robotsuite/__init__.py", line 455, in runTest
    assert last_status == 'PASS', last_message
AssertionError: WebDriverException: Message: u'arguments[0] is undefined' ; Stacktrace: 
    at anonymous (http://localhost:55001/plone/@@dexterity-types line 68 > Function:1:1)
    at handleEvaluateEvent (http://localhost:55001/plone/@@dexterity-types:68:20) 

These errors don't seem to be related to my changes, can you please take a look if it works for you, @tisto or @khink ? Here is the buildout for the security panel migration: plone/buildout.coredev#61

Otherwise it should be good to merge.

Thanks!

Which of the packages above should retain Plone 4 support? So we'd need to do something like: plone/plone.app.contenttypes@2347905
