Incidents emails improvements

[dmanubens-zz]

1. When incidents_email_list is not defined in 'config.php' the emails should be sent to emails of the users.
   In php/utilities/incidents.php line 45, comment avobe, says send to active users only:

$rs = do_stored_query('get_member_listing', 1);

However, if the 2nd parameter is 1 it includes inactive users.

2. Moreover, do you see it feasible to implement something to send just to users/providers involved when selected in the form?

3. Also the message sent does not include the final information of involved people, but identifiers

Yo no he trabajado con los incidentes.
(unicamente adapté los mensajes para que usaran UTF-8, y para permitir en la configuración desactivarlos)

Así pues en principio no intervendré en este issue.
