refactoring regarding AppTasks:

- AppTasks are now returned by ActivityResult through all AppTask-Related activities (includes ForwardResult)
 - AppTasks are now passed correctly even when using search (this fixes a problem that AppTasks like SearchUrl were not passed to EntryActivity so the App didn't return to the browser automatically)
 - AppTasks are deleted by ActivityResult or by checking for LaunchedFromHistory

Added option to leave app with db unlocked (this is even the default now!)

Added missing EntryActivity files
