#20 Changes to dialog showing multiple results

[Jesper Kamstrup Linnet]

When the search for implementors finds multiple
results, a dialog is shown. The current format shows
the method first - and requires the user to scroll to
see the full package/project of the actual implementation.

The dialog should be changed to:
- Show the package and project as the first elements
- Save the size (and perhaps the position of the window).
