Notes

When a user sends a complaint, every admin with rights immediately receives it. 
By default, Ventrilo has 'Auto open' checked in the complaint window, so it opens immediately.
Auto open is a client side only setting.

Offsets 24+ only exist in subtypes 1 and 3
Offset 24 is a uint32 of value 0 in subtype 1, a VentriloNetString in subtype 3
The next item is a VentriloNetString (both 1 and 3)
In subtype 3, there is another VentriloNetString after

There are a lot of pieces of the 0x56 packet that are always 0, noted in stucture.

If the user being complained about logs out (even if they log in again) before the complaint is 
sent, ventrilo generates 'The intended user is no longer valid', and no packets are sent.

If nothing is types in the complaint message, ventrilo generates 'You must provide a reason why
you are sending the complaint.', and no packets are sent.
