  Improve the Load dialog's UX when there are no save files or corrupted files

Re-add the popup that appears when "Load" is pressed on the title screen if
there are no files, but now check for files from previous versions too.

Improve handling of switching from a version with files to a version without
files, disabling buttons on the load dialog when there are no files in the
current directory. Versions with no files will still be shown in the drop-down.

This adds a todo about the error path at the start of evaluate_summary_string,
this path is reached by creating empty files in the save dir. The dialog's state
is reasonable, so it seemed a low priority and I don't want to introduce new
bugs by refactoring this path now.

Deleting all files now doesn't automatically close the dialog.
