* godmode/agentes/alert_manager.php: Added support to disable or
enable an alert. Improved a bit the interface to make it cleaner
because the modules are a bit separated now.
* include/functions_alerts.php: Added support to disable or enable an
alert via set_alerts_agent_module_disable(). Added a flag to choose
wether to get disabled alerts on an agent or not.
* ChangeLog: Style correction again. Please, be careful.
