- fixed the Tcl Command Delete to have an argument -f that will force deletion evading the popup (if the popup is enabled). The sme command without a name now will delete all objects

- fixed the Tcl Command JoinExcellons
- fixed the Tcl Command JoinGeometry
- fixed the Tcl Command Mirror
- updated the Tcl Command Mirror to use a (X,Y) origin parameter. Works if the -box parameter is not used.
- updated the Tcl Command Offset. Now it can use only -x or -y parameter no longer is mandatory to have both. The one that is not present will be assumed 0.0
- updated the Tcl Command Panelize. The -rows and -columns parameters are no longer both required. If one is not present then it is assumed to be zero.
- updated the Tcl Command Scale. THe -origin parameter can now be a tuple of (x,y) coordinates.
- updated the Tcl Command Skew. Now it can use only -x or -y parameter no longer is mandatory to have both. The one that is not present will be assumed 0.0
