Updated content notifications
Slideproof should provide notifications to users about slides that have had its content changed, i.e. deal stats updated or a design feature tweaked.
It would be handy in either of the following forms:
1. via 'check', it could list the data that has been updated and which slide they should replace it with;
2. by little icons that show on the slides within the library, like a green circle to indicate that slide has been recently updated.
3. a notification window that pops up (like the 'check presentation' window that already does) that says e.g. "please note [slide name] has been updated, please ensure you're using the most recent slide"
4. like Microsoft Word does with spelling and grammar, it could underline content with a red squiggly line that indicates this content is out of date.
5. all of the above.
