Fix search for unsaved files
Search for unsaved files doesn't work because we don't have QUrl's for them. Instead use KTextEditor::Document pointer for such files.
Included is a small fix that I noticed while working on this. If you try to replace checked after searching, the file that you have opened doesn't get highlights as it should.
Possible further improvements:
- Ask main window for the "tab title" of the doc so that we can use that in the search tree view. Otherwise its kind of really ambigous
