Have the checkbox be checked when uploading AIML files to clear the previous file entries.
It is not clear to me why you would ever want to leave previous possible bad AIML entries in the database when loading a newer version of an identical file. Having to check the checkbox just adds another step in a tedious process.
I would think you would always want to remove the previous file entries when uploading it again after making changes.
Having more than one file be loaded at a time would be a nice improvement too. Much like the Pandora bot does with five lines of upload files.
