When you load a session, if file or folder doesn't exist, alert user and disable some functions

Hi chelh,

I noticed that if you load a session, and file or folder doesn't exist anymore, there is no alert to the user (maybe apply would display a message, I didn't test).
I would suggest something like this:

• Disable Apply, make sure "OK" perform only the "Quit" part of "Apply+Quit" (or disable OK as well). Optionally, Refresh and the ListView could be disabled as well.

The ListView kept the list from previous session, so depending on your implementation, there might be a risk to publish or extract files from previous session instead.

Thanks!
