[IMP] web_editor, website, *: use new color names

*: mass_mailing, website_blog, website_forum, website_hr_recruitment

Deprecate alpha, beta, gamma, delta and espilon color names and now use
a new color system: o-color-x, with x from 1 to 5.

This will allow to review the colors of all themes to have nice visuals
for the new color combinations classes, without breaking the current
uses of bg-alpha, alert-delta, etc in current websites of customers
(by keeping the old color and classes for compatibility).

This will also allow to uniformize all themes under the same conventions
to enforce BS color override:
- o-color-1 used as primary (as before, for alpha)
- o-color-2 used as secondary (as before, for beta)

Before, some themes were not following the 2 guidelines. The users
using those themes will simply have the possibility to choose o-color-1
and o-color-2 colors accordingly to restore their website without
breaking the new system features.

Another change is that those colors are defined through color palettes
and not theme color palettes. This will avoid them to generate automatic
bootstrap classes which we don't want (alert, btn) and generate the one
we want by ourself.

Note: for mass mailing, the colors and classes also have been renamed
but the system stays unchanged.
