Refs #9077 Modified checks, File-> Close and Coadd

The following has been fixed:
* File->Close Refl Gui now actually closes it, as until now it had loaded help.
* Clearing, reloading or opening a table will now do a modifed check and offer to save
* Clearing the table no longer sets the mdoified flag
* Coadding workspaces now works as intended
