Fix reloadAll by adding option to showModOnDiskPrompt() to ignore/include non edited.
After the change to remove the modified-on-disk dialog, reloadAll() stopped reloading files modified on disk. It only reloads unedited files, which makes the reloadAll functionality almost unusable. Basically only clearing undo for files that are saved.
The fix is to not ignore non-edited, but modified-on-disk files in reloadAll().
