I just change completion engine to use ManagerClass's InitCompiler and
LoadExternalLibraries instead of performing operations copy pasted
from there.

I think the main objective is to make ManagerClass.Run method more
flexible (it should call a bunch of virtual methods for every step or
run a pipeline on small "compiler step" structures), so completion
engine could just specify what is desired (recreating the hierarchy
tree, parsing one file, or one method) and call Run from base class.

Also I wonder if Options.PersistentLibraries can be used by completion
engine - it avoids loading of libraries and creating hierarchy tree
for them in several compiler runs.
