Add view and property-sheet for Specialise Divergence Tester so that only specialise links of specific portal types can be divergence tested (or, alternatively excluded from divergence testing).

Use the accessors above to restrict which specialise links are selected for testing on the movement by the Specialise Divergence Tester.

JSON allows to exchange python dictionaries in safe and simple way.

So thanks to using directory where test results are posted, it is possible that call
external tool will call erunTestSuite, which would later attach to such directory
"x" and do "something" more with stored test results.

Now is possible to run these tests under portal_classes due the "magic" done by runLiveTest and also run using runUnitTest.

This can happen, for example, when there is a broken subobject on a
property sheet.
The main advantage of this change is to make the error cause easier to
track down.

Whatever the reason we exit this code, we are not generating this portal
type anymore. So remove it from set.

simulation_movement.setPropertyList(
  'variation_category',
  movement.getProperty('variation_category_list'))

Does work after all. Note the absence of the _list suffix on the setting
property.

If a mapped property had a '-', it would be called like:

document.setProperty('-price', -20.0)

Also, add a warning about trying to set 'variation_category_list' in a
SimulationMovement with property mapping.

66cb9c96 prevented init scripts to be used to
set default values, so original order of initialization must be reverted.
_edit may also trigger interactions that require workflows to be initialized.

Code simplication is kept, and _edit **kw is now passed to init script as an
alternate way for init scripts to know properties given to newContent.

Applying mixin classes dynamically under portal types, does not allow to overwrite the methods which already exists in the inherit tree for the methods provided by the mixin class.

So with this new document (WebSite.py), we can force which implementation must be used in that case.

This reverts commit 688cf160.

This fixes a regression in 66cb9c96

That property can be used to request more databases in a given suite.
This removes the need of fetching an hardcoded number of connection strings
at an hardcoded position in mysql_db_list, which in turns fixes a python
mistake ("string + list").

With this mixin enabled it is possible to handle the PUT methods for document creation.

ShaDir reuses the code of ShaCache.  WebSection_putFactory takes care about publishing the document.

It is required to publish the document, but it can only be done after all.
Otherwise, it can lead in security problems.
