Unfinished and not fully working scope analysis for types.
Original work was started some time ago in#233 and this PR contains all changes rebased to current master

some of changes got migrated outside of this PR to master already and are dropped from here

This is early stage of updated scope-analysis with types included into scope, there is still a lot to do.
