[Devel] New module: statistics script support

[Bogdan-Andrei Iancu]

Hi,

The devel version contains a new module - statistics module: The 
Statistics module is a wrapper over the internal statistics manager, 
allowing the script writer to dynamically define and use of statistic 
variables.

By bringing the statistics support into the script, it takes advantage 
of the script flexibility in defining logics, making possible 
implementation of any kind of statistic scenario.

All statistics variables defined via this module will be registered as 
"script" to the statistics core manager.

Ex. of usages:
    - count number of requests based on types, body, destination, 
source, etc
    - if signalling is reliable (lossless), to count active calls to a 
destination
    - whatever else yo can imagine :)

for more info, please refer to the online documentation:
