[Design] Auto-Export Collection and Settings Dialog

[Mimi Yin]

Hi Heikki,

I downloaded the latest end-user trunk build and I noticed the new  
'Automatically export your collections and settings so you can  
migrate' dialog. It popped up when I tried to quit Chandler.

The pop-up felt a little out of place.

Perhaps instead, we should change the 'Export Collections and  
Settings...' menu item to an 'Upgrade...' menu item that pops up the  
following dialog:

===
Upgrade
-----

[Chandler Logo]		Upgrading is now a simple 2-step process:

					1. [Check] to see if there's a new version of Chandler.

					2. [Export] your data in preparation for upgrade.

															[Cancel]
===

Thoughts?
