Display a CrashFrame warning at startup if the application is running under applet mode.

Other changes include:

* defines: added NON_MOVEABLE macro.
* AsyncTask: set class as non-moveable, too.
* RootView: provide an override for getDefaultFocus().
* StatusInfoTask: replace GetStatusInfoData with IsInternetConnectionAvailable().
