Scheduled Task File Permissions Audit module

[lampnout]

This PR is opened to add the module "ScheduledTasksAudit" (implemented in ScheduledTasksAuditCommand.cs) on Seatbelt.

The module is hunting for privilege escalation vectors in scheduled tasks by investigating the permissions of the files each action runs.

In summary, the following logic has been implemented:

• enumerate the scheduled tasks
• apply certain filters to select and investigate scheduled tasks that run under the context of user accounts other than the user that runs Seatbelt
• check the file permissions of each action looking for permissions that would allow an attacker replace (or edit) the binaries the scheduled task runs
