RT::System is a simple global object used as a focal point for things that are system-wide.
It works sort of like an RT::Record, except it's really a single object that has an id of "1" when instantiated.
This gets used by the ACL system so that you can have rights for the scope "RT::System"
In the future, there will probably be other API goodness encapsulated here.
Returns a hash of available rights for this object. The keys are the right names and the values are a description of what the rights do
Create a new RT::System object. Really, you should be using $RT::System
Returns RT::System's id. It's 1.
Since this object is pretending to be an RT::Record, we need a load method. It does nothing
