Arseniy Shestakov 9fd1cff090 Refactoring: always use std prefix for shared_ptr, unique_ptr and make_shared
Long time ago it's was used without prefix to make future switch from boost to std version easier.
I discusses this with Ivan and decide to drop these using from Global.h now.

This change wouldn't break anything because there was already code with prefix for each of three cases.
