@brief Provides generation of unique SessionItem itentifier.
 
In the future might be turned to singleton to keep track of all generated identifier
and make sure, that SessionItem identifiers loaded from disk, are different from those
generated during dynamic session. For the moment though, we rely on zero-probability of
such event.
