Javascript Callbacks in fact sheets

For ARIS Connect the Javascript handling of the fact sheets needs to be extended to support callbacks for the edit mode (contribution). The JS-functionality in the factsheets needs to be informed, when the edit mode starts and when it ends. This has to happen before the refreshing of the fact sheet (item component), so that the javascript functions can save their state. This would be similar to the lifecycle methods of the JavascriptPlugins in Connect and would allow to write more interactive fact sheets in customizings. These callback functions should be clearly documented.
