Avoid duplicating web addon in enterprise by extracting a common basis.
Enterprise features stay in enterprise, but use that common basis.

Mainly:
 - JS refactoring and linting
 - Conversion of .sass into .less split into multiple files
 - Templates cleaning and DOM simplification
 - Re-generation of web.pot, and update of .po files

In 9.0's 05adb7f the `<div class="address_format"/>` wrapping an address
city, state_id and zip fields was removed.

There is a hack on fields_view_get which transform this block depending
on the company country, so without the block the feature isn't enabled.

This commit adds a class on the new block `<div class="address_format"/>`
used to wrap the whole address which will change the sizing of the city,
state_id and zip fields as it was before version 9.

To fully follow what was done previously, the zip is aldo moved before
the city if the address format needs it.

Thus we now have as before the three format as follows:

[default format]

city state zip

[format .o_city_state (brazil)]

city state
zip

[format .o_zip_city (belgium, netherlands, ...)]

zip city
state

Another change is brought by this commit, before most element attributes
from city, state_id and zip fields were lost whilst doing the hack, now
they are all kept.

The default comportement of tags has been changed. The default color is now visible on kanban.
The 10th color is now invisible.

The settings views are now using radio buttons which are using labels.
These were set to bold by bootstrap. Now force font-weight normal for
labels which are not labels inside an oe_form_group_cell_label (field
main label).

If there is no field 'color' on tag model, the colorpicker should not be displayed.
