If two views are open and user holds down Ctrl+Alt and doubleclicks, the word is highlighted in both tabs. (Can't use Ctrl+DblClick since that is now occupied by delimiter select). The patch still allows for independent highlighting in both views with a normal double click.
I had to refactor some code. FindReplaceDlg::processRange() always used the member variable _ppEditView, but what was needed was a function where the view was passed in as a parameter. SmartHighlighter::highlightView() has been broken up a bit, and has gotten a new overload where you can send in the string you want to highlight.
