Title: Sergey menus

@ussuri

- Added modal dialog support. I created new widget for modal (may should be an attribute).
- Fixed bug with selectors and overlays stealing events. Add/Remove listener needs to canonicalize the closure. This fixes when a menu or dialog appears the next click in the file viewer will cause the toolbar to disappear, spliter to not track and ace editor selection can be messed up.
