ERP5's Code mirror supports viewing history of editions using codemirror's merge mode ( http://codemirror.net/demo/merge.html ).

This was enabled for portal_components, but not for web pages.

This moves the methods used by the components in a mixin class and make `TextDocument` class use this mixin.

This way, we can benefit from diff view on web pages as well:

@romain @vincentB @katomaso unless this interfere with your work of making codemirror works in renderjs ui, I think we can enable this. It does not include any change to codemirror code, just enable everywhere what was available only on components.

@klaus I did not check, but we probably want this enabled for PyData Script as well.

It was "dead code", this form was not used in any action.

Fields were not following naming conventions, so search would not even
work.

Because we generate search dialogs based on module listbox, organisation
module already had a working search dialog, so this dialog is not needed
anymore.

This is not used anywhere, and actually cannot be reused anywhere because
of hard-coded document identifiers.
It is too trivial to be worth salvaging, so drop it.

- Text was not converted into HTML.
- HTML was converted into Text before rendering.

- some method names were changed to make them clearer
- new intermediate class 'SlapOSTester'

- method waitInstance moved from runner to communicator
- new simple methods in communicator for request and wait instance
- new methods to modularize runner code
- communicator initialization code moved in runner

Variable name changed from jsonData to json_data.
Old comment deleted.

Some methods in the slapos master communicator no longer exist. The unit test for scalability was updated accordingly.

An update in zope.testbrowser dropped the mechanize dependency used by the browser. Now it uses WebTest instead.

Details of the update: https://pypi.python.org/pypi/zope.testbrowser/5.2.1

- Most of the communication with slapos master is done using the new Slapos Master Communicator instead of Slapos Controller:
  * supply, request, check instance status, check software status.
- Refactor of related methods (waitInstance, isSoftwareReleaseReady, etc.)
- Initialization of communicator: initialize connection to SlapOS usign key and certificate
- General refactor and cleanup: some unnecesary sentences, comments and methods were removed.

- The base of this code comes from some work done by Rafael in here:
    https://lab.nexedi.com/nexedi/slapos.toolbox/blob/master/slapos/agent/tester.py
- Refactor in communication with slap objects for supply and request.
- Added method to check if instance is requested.
- Refactor in log calls.

Each step was still sending emails, not only the controller. This is not
useful.

In the report code, this at_date is used and report generation would
fail if user does not select an `at_date`.
