new version lz11-V2-1.1

Release Notes lz11-V2-1.1:
This version supplies some additional features:
- The installer can be called by ./lz11.install --debug, which will produce BMP files instead of paper prints (for test)
- Now the cups-restart is done also properly for Debian and Gentoo
- An installed Z11 printer-queue (PPD) and its options are updated automatically during installation
- The print-job cancelling is now appropriate for hotplug generated devices. Printer "hick-ups" on a resume are prevented
- The print-job cancelling is shown automatically in an "xterm"
- some smaller bug fixes

Have a lot of fun
Yours lz11-team
