Version 1.69: Updated to only use console.inkey() for user input and not use console.getkey() anymore.  Also, SlyEdit will now write the editor style (ICE or DCT) to result.ed at the end when a message is saved.  Also, when editing a message, if the cursor is at the end of the last line and the user presses the DEL key, then treat it as a backspace.  Some terminals send a delete for backspace, particularly with keyboards that have a delete key but no backspace key.
