#306 Prompt on exit to save current layout

[Mountain_Geek]

Thanks for all the work you've put into Console. I'm using it for Rails development and it's great. The one important thing that seems to be missing is the ability to save the current 'workspace' (open tabs and their positions and current directories in each). Unless I'm missing something I have to setup a different config file or a different shortcut with new command line options to do this. That would mean I have to do it each time I quit in order to have my workspace restored to where it was last time I used it. It would be great if Console would ask to do this for me from the current layout on close. Thanks for considering it!
