Remove the snapshot video output 

It is not used anywhere (it was meant for use with Corba).
We have better ways to take snapshots nowadays.

* This module is a pseudo video output that offers the possibility to

* The snapshot structure is defined in include/snapshot.h
* In order to access the current snapshot cache, object variables are used:
* vout-snapshot-list-pointer : the pointer on the first element in the list
* vout-snapshot-datasize : size of a snapshot
* (also available in snapshot_t->i_datasize)
* vout-snapshot-cache-size : size of the cache list
*
* It is used for the moment by the CORBA module and a specialized
* python-vlc binding.
