Restore code completion and help for imported plugin types

Code completion and member help stop working for plugin types referenced through an imported namespace. For example, after Import Einhugur.GraphicsFormats, declaring Var png As New RawPngImporter() produces no member suggestions or help when typing png.OpenFromFile. Declaring the same variable with the fully qualified type name, Einhugur.GraphicsFormats.RawPngImporter, works.

Imported plugin types should provide the same member completion, descriptions, hover information and parameter help as fully qualified plugin types. Using the fully qualified name is the current workaround.
