KPIs and tips by email.

Today, Odoo is really tricky to use without seeing the screen, it must be improved to be usable.

Commit https://github.com/odoo/enterprise/commit/8ac1c19fac7615fecd51e670f798d13158a4e53c
changed the odoo interface violet by changing the main LESS variable
but forgot there was many direct occurences in XML/HTML/... (for
example for the mobile browser color).

Even if it's community the odoo interface violet is used at many places
(module description, XML demo data, ...).

This reverts commit b4d7b7e6dc91d92e9f57479ddf5f691d1fc04ba8.
Odoo always uses term eCommerce

No functional changes, only rewrite the code with
the api.v8 which more pythonic and smooth.
