recent files: hide no-longer existent files

[a773music]

scide shows recent files even though they are moved, removed or renamed on the file system. I propose something like:

At startup check if all rentries are present, those that aren't are marked as nonpresent (and not listed in the menu). On next startup, check again, also those that are marked as non present (maybe they're valid again), mark non present ones and don't show them.

That way the user can move files around and still use recent files.

The proposed idea to track inexistent recent files but not display them would demand a change in the configuration file format. We certainly can not do this for SC 3.6.x

We could simply remove inexistent files from the recents list, but then again, I wonder where's the big benefit... I'm not decided over this, so I'd like to hear more opinions...

A basic checking of existence of files, remove from list if not, would be enough.

The benefit? Well when scide invites the to click somewhere that doesn't take me where I expect, it's not a good user experience. If I move a file around, I'll see all the places from which I opened it in recent files, but only one is valid. Although the valid one is most likely the top one, I have to dissect the path and decide where to click.

Granted, some people would never use the recent files feature, but for those that do, I think it would enhance the experience to show only files that exists and that actually could be opened...
