A shape is made of different colors which are mapped to user color
combination colors (e.g. if a shape use the #3AADAA color, it is by
default mapped to color combination background color n°4). We allow
to add other arbitrary mappings for each shape should a theme want it,
thanks to another created class. This is especially useful for header
and footer connections in default generated pages where the combination
of classes "o_web_editor_Airy_12 o_footer_extra_shape_mapping" will
use a color mapping using the footer color if the theme configured the
Airy 12 shape to do so.
This commit also modifies the generation of pages made by the website
configurator to automatically add the header and footer respective
classes on first and last shape if one is found (if one is found but
should not have a specific color mapping, this is not a problem as the
class has only an effect if the theme declares it).
