This reverts commit ddcb5001.

This commit itself is good. But some more work is needed to
check failures that were hidden

In poppler 0.18+, pdftohtml generates " " instead of " ", so
make sure both are accepted.

_getOb() is too low level and is no longer called by Zope during traversal (which uses
__getitem__()), if the object is not an explicity subobject.

__getitem__() is the right interface for a folder to pretend to have objects it
doesn't actually have.

same as bcc12a28 (use getattr to be compatible with newer zope version).

since Zope 2.12.23, ObjectManager's get and __getitem__ returns only 'items' (no attributes / methods from the class or from acquisition).

since Zope 2.12.23, ObjectManager's get and __getitem__ returns only 'items' (no attributes / methods from the class or from acquisition).

testERP5WebWithDms will pass now as librsvg is well installed now and
assertion on tests were simplied to become more reliable (it provides
less false positives for image comparation).

The functional test testSurchargeWithInvalidDateTime was improved for
better assertions.

This fixes test_getInstancePropertyAndBaseCategoryList
and also removes obsolete 'updatePropertySheetDefinitionDict' methods.

This reverts commit 51d40d1e.

Use colors can generate little diferences at the outcome comparations
between the computers, so black and white is enough for the test purpose,
to compare if the background image is showed or not.

fix svg definition as in some images the namespace is not
well defined by using xmlns="http://www.w3.org/2000/svg" instead
of xmlns:svg="http://www.w3.org/2000/svg"

Those are the cases of the images generated from OO to SVG conversions.

The image comparation isn't advanced enough to identify minor color
 changes when convert to grey scale. So use simpler images to make
sure we do not get false positives.

The goal of image comparation is only for make sure background is
placed at the figures.

With imagemagick providing a good support for rsvg-convert, those failures
are not expected anymore.

This merge include fixes for some functional tests and
testRunMyDocConfiguratorWorkflow.

add test to check that the method getInstancePropertyAndBaseCategoryList returns properties from property sheets correctly

Extend method getInstancePropertyAndBaseCategoryList to be possible get property sheets from portal_type objects i.e portal_types/Foo. And refactor code to get properties from object inside portal_property_sheets i.e SimpleItem, DublinCore

which is not correct.
