[Lazarus] CodeTools knowledge about a project - find a class

[Kostas Michalopoulos]

Actually it works fine, after peppering the code with writelns to see the
flow, i figured out what was the issue: there is a 10 minute interval (by
default) between saves and the dictionary is only saved at the interval. I
expected it to be saved when exiting the IDE regardless of when the last
save was.

I added a Save; call right at the beginning of the OnIDEClose callback,
like this

procedure TCodyUnitDictionary.OnIDEClose(Sender: TObject);
begin
  Save; // Save the dictionary before closing the IDE
  fClosing:=true;
  FreeAndNil(fTimer);
end;

And it seems to behave as i expect it now. This way it wont lose any data
when i restart the IDE (which i do often when working with custom controls).

TBH i'm not sure the approach of only scanning what you have loaded is
enough since it still wont show anything from a unit i haven't already
loaded before. For example if i show the dialog looking for TGraphic it
will only show up after i have already used it at least once. So if i have
an empty database i get this:

1. Open the identifier db dialog (i have set it up as Alt+`)
2. Start typing TGraph
3. Nothing shows up
4. Press Ctrl+Space in a form code (e.g. Unit1 in the default empty project)
5. Start typing TGraph so that it shows in the completion dialog
6. Press esc to cancel the completion dialog
7. Open the identifier db dialog again
8. Start typing TGraph
9. Now TGraphic (and other stuff) show up

I think there needs to be a way for the dialog to also know whatever is or
can be known with the currently loaded packages and units, not just
whatever you have encountered so far. That information seems to already be
available in the IDE in other places.
