Use Bamboo-generated tokens as method of authentication when accessing webhooks (e.g. remote trigger, specs scanning)

Currently, remote triggers make you enter every possible IP/CIDR address that a remote trigger is forwarded through. This has been done for security reasons, however it's an extra burden on users.

It would be good if there was an option to relax the security settings for remote triggers such that only the last IP was necessary, or none at all (if the server already requires auth for the trigger, as it does in our case, it seems unnecessary).

Even better, changing the system entirely to use Bamboo-generated tokens would both increase simplicity and security.
