# DeleteTab script (Alt-del):
#       - This script will delete the current tab
#       - It will determine if the tab was already saved or not
#         * if the file was saved previously, we simply delete the file
#         * if the file was not saved previously, we close the tab without changes and without being asked
#       - Initially this script was a Notepad++ macro but it lacked some essential functionality like deleting/closing an unsaved tab.
