MiniPauker Code

2. When using the 'Save & Quit' and there is no current session to save into then a confirmation dialog is shown
3. Fixed an exception when a task such as session load is running in the background and you try to import a file (it will be stopped before it can do anything and the ExplorerUI.updateView will then fail for having an empty file list - fixed by opening the previous instead of next view for a task that didn't run)
