Before this commit, the customization dialog for themes was not
multi-website. That means if a theme was installed on a website, the
customization dialog was enabled for all the websites.
Note: this commit uses the '_post_copy' system of theme installations
for the first time and it had to be adapted a little bit.

The purpose of this task is to make the customize dialog as generic as
possible, that is theme-independant:
1) The design is now totally generic (Odoo visuals)
2) The XML definition is form-view like. This allows themes to extend
the dialog without any risk of breaking the style and also allows to
not care about lots of technical details.
3) New options have been included. Those were themes options that are
now generic and which themes can simply adapt without touching the
customize modal (navbar colors, footer color, navbar layout, fonts,
body background, ...).
The color palette can now also be customized with user colors.
Using sass functionnalities, color palettes and fonts integration is now
a lot better.
Thanks to @qha-odoo for the original design.
