#21 Fixup for 'click off' that saves edits.

[John Clayton]

Should fix the image panel code so that when an entry is changed, or an action takes place that redraws the entire grid, or a new entry is selected we DON'T lose the current changes that have been made to the entry.

For any of these events, I need to ensure that editing is STOPPED (not cancelled) prior to letting the event continue.

Existing code will handle what happens when the edit is stopped, just need to intercept some more events and make it happen more often.
