[IMP] Mail: Add optional activity domain for systray

Addition of this optional 'domain' value for systray activity related
lines allows the restriction of which activities will be included in
the view opened when the line is clicked on.

One use case is when a model is split between 2 systray activity lines.
In this case we most likely do not want the same activities of the
model to show up when we click on either line. For example, say we
have 2 modules using the same model, but the module instances of that
model are distingushed by a field.Selection value. Then we would only
want to show the activities related to each module when we click on
their appropriate systray activity lines based on that field.Selection
value.
