Add test to simulate the issue with the method TemplateTool.installBusinessTemplateListFromRepository

Using the method try to install Business Templates that are already
installed, the Business Templates is uploaded on ERP5 but not used. It
creates a lot of garbage because in the end you have many bt5s not
installed.

The logic of all Configuration Items was not changed, but now the
changes are applied only if fixit is True and the constraints are
filtered by constraint type equal configuration.

Cosmetic: Trailing whitespaces were removed in the same commit

Also, Added constraint property sheets to Script Constraint portal type

Otherwise with CKEditor it's not possible to add some text outside of quoted
content

As MKCOL_handler() is not implemented on OFS.Folder.Folder class, the one from
ERP5Site was acquired when calling webdav.NullResource.NullResource.MKCOL().

When a portal type acquire role, it should place the role definitions in the same local role group ids

This reverts commit 1e90e4f8.
missing commit message

- we only want to sum transaction in the period when there is a from date.
- when from date is passed, really get period start date from from date

still keeping backward compatibility with older python_memcached.

instead of waiting for (long) timeout.

[Before]:

Where:

  in Supply or Delivery(Sale Order, Sale Packing List,..)

When:

( document.edit(something=some_value)

  OR

  document.validate(), document.start() something when workflow transition  )

AND

  document contains more than 100 sub objects, like 100 lines.

Then:
  /some_module/document/1/recursiveImmediateReindexObject
  /some_module/document/1/reindexObject
  /some_module/document/1/1/recursiveImmediateReindexObject
  .
  .
  /some_module/document/1/100/recursiveImmediateReindexObject

are triggered.

The first big recursiveImmediateReindexObject recursively reindex all the sub
objects. Thus the following reindex are duplicated.

[After]:

Reindex:
  /some_module/document/1/reindexObject
  /some_module/document/1/1/recursiveImmediateReindexObject
  .
  .
  /some_module/document/1/100/recursiveImmediateReindexObject

The root recursiveImmediateReindexObject is removed.

This has been the expected behavior from the beginning.
Before was only a side effect by giving empty dict to "if activate_kw == None"
expression.

ZODB Components/Python Script: Add link on Zope HTML traceback to go straight to the source code line.

ZODB Components: Like Python Script, use Ace Editor annotations to check source code without saving.

Also, switch to Pylint for Python Script source code checking to use the same
code for both.

ZODB Components: When checking source, improve message when a SyntaxError is raised through compile().

ZODB Components: Disable spurious Pylint warning: 'Access to a protected member %s of a client class'.

These are completely useless and create conflicts with VCSs.

because ID should not contain whitespaces.
This reverts commit e6cd717e.

Publishing "activate" is generally harmless, but creates (with current
publisher code) two failing activities, causing unnecessary noise.

...when COLUMN is not a valid column (hence mutated to a STRING_PREFIX
token at lexer level).
Kudos to Tristan for triggering this bug.

insertbefore instead of insertBefore.

Finally removes the need to hardcode transition id when it's the same as
current transition (which should be the case in the overwhelming majority
of transitions).
