A new option to display the program output in a "no-fency" mode was added, as well as a --configure option. The colored output code has been improved, and no longer causes the background color to change if knocker is executed in an X11 terminal. The text is now correctly displayed on transparent background terminals. This release adds the options --last-scan, to perform the last port scan again, and --last-host, which puts the last scanned host as the target.
