Subject: [IMP] web: float_factor and float_toggle widgets

This commit provides new js widgets for list, kanban and form
views on float field.

1/ 'float_factor' displays the normal float field, but takes a
conversion factor as option. The displays value is the normal
one multiplied by the factor.

You can use the widget like
<field name="my_float_field" widget="float_factor"
option="{'factor': 2}"/>

2/ 'float_toggle' displays a button (in edit mode) looping on a
range of given value at each click. A conversion factor is optional
(default will be 1) to display a converted value, but sent to
non converted one to the server.

You can use the widget like
<field name="my_float" widget="float_toggle"
option="{'range': [0, 0.5, 1], 'factor': 2}"/>

'range' and 'factor' are put in the options.
In simple read mode, the widget display the value as a traditionnal
text (like a normal char field).

This commit provides tests and documentation for those 2 widgets.
