A "}" was missing.

Issues #195, #193, #192, #178

The send_purge_demand_mail() is now going to send an alert mail to the
nG6 admins if a purge demand already exists for a given project, instead
of creating a new one.

Issue #192

New function get_multiple_purge_demand_mail() to warn the nG6 admins
that a purge demand already exists for the given project.

Issue #192

New check_demand_insert trigger to prevent the insertion of a second
purge demand for a given project.

Issue #192

The function add_purge_demand() will not update the run and analyzes
tables if a demand already exists for a given project. (See new trigger)

Issue #192

Function "resend_purge_demand" reworked to ignore hidden runs and
analyzes.

Issues #178, #193

The hidden runs and analyzes do not appear in the mail or volume count
anymore.
Next : the resend function.

Issues #178, #193

2 functions have a new parameter 'get_hidden'

Issues #193, #178

'CC' headers have to be reset not to display "esitoul" 10 times.
