[Users] NEW: ACC module - new multi-leg format

[Bogdan-Andrei Iancu]

Hi everybody,

with the new ACC changes, I introduced a new format for multi-leg 
accounting.

The overall behaviour is the same, but it's a more flexible approach - 
instead of having a fix logging frame (source and destination), the 
script writer has the liberty to define whatever and how many fields to 
be logged for each leg. All this is controlled via a single module 
parameter - the "multi_leg_info". See:
    http://openser.org/docs/modules/1.2.x/acc.html#AEN248

Regards,
Bogdan
