A new test suite to perform static check on business templates using  `CodingStyleTestCase`.

This runs a coding style test for each business template, after installing the business template and its dependencies listed in business template metadata.

---

In order to start with a test suite with no failure, business templates that does not pass this test today (because they don't install or because pylint issues still needs to be reviewed) are skipped with an ad-hoc  `bt/skip_coding_style_test` in the business template. Note that this file is not created by business template system as it is a temporary measure, business templates must pass pylint and other checks from `CodingStyleTestCase`.

---

I took the approach of creating one independent test per business template, instead of the approach of creating a site with all business templates like we did in testNamingConventions or testHTML. This appears as another "Coding Style" test, like Performance or Scalability tests.

The idea behind this was that if we extend our business template checks ( for example when we translate the [ERP5 Module Creation Guidelines](https://www.erp5.com/documentation/developer/guideline/module) to some scripts we can run on a business template ), we can check that each business template contain what it should contain and not just that the global result is OK.

PortalTransforms: safe_html: Changes in b255c894 were not actually applied so merge FS module and portal_transforms/safe_html.

These titles duplicate listbox configuration, preventing any change from
reaching users (...who customised their listbox).
Also fixes cases where column title was stored in selection after
translation, which breaks some reports.

Avoid double-calls when one is enough.
Avoid unused locals.
Avoid repeating conditions.
Inline single-use expressions.

Bootstrap is actually the automatic migration of tools. It happened to me
several times that I mistakenly start an old instance on a too new version of
products and this instance is migrated automatically.

By leaving a note in transaction it's easier to find out which
transaction performed the automatic migration to revert to the state
before using technique such as
https://blog.gocept.com/2019/06/14/undo-transactions-by-truncating-zodb-data-fs/
for FileStorage.

with this change, a command such as;

    python -m ZODB.scripts.fstail -n 20 ./instance/slappart6/srv/zodb/root.fs

show something like:

    2019-11-12 02:46:42.106313: hash=44fecb9a63411fbf305cea82f4c699c478000d61
    user=' None' description='/timer_service/process_timer\nSite migrated' length=462938 offset=881877846 (+70)

for the transaction which did the migration, so it's easy to repair.

Also, ZODB Components Transforms modules were 'Document Component', whereas
it should be 'Module Component' (introduced recently) considering that they
have no Portal Type.

We'll gradually enable the business templates as we fix them.

ZODB Components: PortalTransforms: No need to reload() 'erp5.' dynamic modules as this done through reset.

Calling manage_reloadAllTransforms was raising KeyError.

ZODB Components: image_to_{bmp,pcx} have already been migrated but the filesystem modules still existed.

You may have to either restart your instance or call portal_transforms/manage_reloadAllTransforms
for this change to take effect.

This is a mirror of the late import of getCurrentNode within
product/ERP5Type/Core/Folder.py
Both are required depending on which module is imported first.

This reverts commit 0af3e8f6.

This is not required anymore since ERP5Type.PropertySheet is a dynamic module
(commit 9ddcbfc1).

from a41f71c3 :
> Remove the TALES for lines, columns and tab on the matrix box because
> the default behavior is to call this updateCellRange script

that's not true, we have to list the asCellRange script explicitly.

ZODB Components: ModuleSecurityInfo() should also apply to the alias module, not only to the versioned one.

This fixes an Unauthorized error when GitLoginError is imported from
erp5.component.module.Git defining ModuleSecurityInfo() for __name__
(erp5.component.module.erp5_version.Git).

Note that when migrating the content of a Product, ModuleSecurityInfo() first
parameter must be __name__.

because pylint/astroid uses string_build to evaluate the named tuple and the source code enabled 
unicode_literals future, string_build is called with an unicode object.

To avoid duplicating _processSearchValue.

Scriptable keys are already handled by other branches below.
If one wants to provide a string or dict value to a scriptable key, they
need to wrap it into another type to disable catalog processing of these
values.

Also, add a missing ignore_unknown_columns parameter.

These are only accessed within methods which are not reachable from
this SearckKey type, so this was essentially dead code.

This allow using measure.updateCellRange to create varianted measures
programmatically.

Remove the TALES for lines, columns and tab on the matrix box because
the default behavior is to call this updateCellRange script
