Work around FileManager/Language issues (IDE-181)

- Auto-complete had no search paths because it had no access to
  the main project view, which did have paths.

- Add hacky, unsafe workaround to issue that FileManager is a
  GUI component instead of separate from the interface.

- This may justify working on new File system sooner.
