Batch operations on objects

[Marius Stanciu]

Add a feature so you can do an operation on multiple objects at once.

Example: if we have 3 objects selected: a GERBER file, a EXCELLON file and a bounding box geometry then if we change the OFFSET field (shouldn't matter on which of the selected objects) then the OFFSET operation will apply to all at once.

In a way, the operations (scale, offset and future ones) should be aware of how many objects are selected and then apply that action over all selected files (objects).

[Juan Pablo Caram]

Also: Toggling visibility with the space bar on multiple selections only acts on one of them.

[Mike Evans]

Or you could copy the last edited offset into the other objects.

On a "it works for me" note, I modified tclCommands/TclCommandOffset.py to allow me to offset all the loaded gerbers and excellons using the command shell. Here's the diff:

-        self.app.collection.get_by_name(name).offset(x, y)

Then in the command line do:

offset all x y

The plot just redraws the display.

I've not done a PR for this as this was a quick and dirty hack to get the job done. I don't think this is suitable for official inclusion.
