[IMP] calendar: Improve color and filters

Now in a calendar view, if we use the color, attribute, it will use
the same color as Gantt views and the color picker widget.

The attribute color isn't more set as default in filter because it make,
in most situation, no sense to filter by color.

Now, we can add new filters in the right panel. To do that, we must
add the attribute "filter='1'" in the corresponding field line.
And if the filter has no direct link with the color of the model,
we can specify an attribute 'color' for this filter line block.
(for example color='color', and the color of the related model
will be used)
