  * added View->Identify to print the device seen to stdout.
    Refactored UsbOpen() / UsbInit() from Plotter.cpp:Cut().
  * added to about message and tooltip. Removed debug page dump on stdout;
  * robocut.spec added, as used in https://build.opensuse.org/package/show?package=robocut&project=home:jnweiger

Also:

* Only preview cutting animation once (i.e. don't loop).
* Filename in window title.
* Disable menu items when no file is loaded.
