[IMP] web_editor, *: add new user value colorpicker widget

* web, mass_mailing, website

Introduced a new sub-widget for snippet options: we-colorpicker. This
allows to retrieve a color value (either a normalized css color or a
theme color name) to be used for a snippet option method.

This commit replaces the old 'colorpicker' snippet option whose behavior
is now simply achieved by defining an xml option using a we-colorpicker
widget in combination with the 'selectStyle' standard method.

This commit also adds the possibility to control the border-color of
elements alongside their border-width. Again, just a we-colorpicker
widget in combination with the 'selectStyle' standard method.

Note: this commit reviewed what the colorpalette palette widget
notifies. This is not a cssColor and a 'isClass' flag to say if it is
a css class or not. The colorpalette always returns a color string which
can be the name of a color like 'alpha'. This is up to the caller to
check if the color string is a css color or not with isCSSColor. In the
case it is not, the related code can read the actual color by reading
the related css variable.
