qsm-odoo dd139948f0 [IMP] web_editor: use inheriting views for oe_structure content
Before this commit, when using the website editor, modifications were
saved in place in the original view. The view was also marked as non
updatable so that when an user migrates its database, he does not lose
its modifications.

The problem with this system is that users were able to keep their
modifications at the cost of having views which are not up-to-date with
the latest odoo updates.

Now, the views' content which is inside an oe_structure element is saved
in an inheriting view instead of the original view. The original
view is not marked as non updatable anymore.

Note 1: we only consider elements with the 'oe_structure' class which
also have an id containing the 'oe_structure' string.

Note 2: if a non oe_structure but editable content is edited, the
original view is still marked as non updatable (however, with the new
multi-website feature, this may not be necessary as the edited view will
be duplicated to be website-specific... we may want to disable the
behavior in a future update).
