Thanks for the pull request!

We can do copy paste stuff now, nice. Definitely a core feature for any canvas editor. I've also noted that you've refactored the custom actions. Very nice!

I've noted the following behaviors:

Bugs:

1. Copy cut pasting 2 nodes linked together would copy 2 nodes unlinked and 1 empty node at coordinate (0,0)

2. The copy cut paste command works across different .xircuits using the context menu, but is buggy when transferring via ctrl + c -> ctrl +v. After closing the other xircuits the issue still persists, so might want to disable this feature in the meantime.

Would be nice to have in future pull requests:

1. When pasting using context, paste at mouse location rather than at the original node position.

That's all for now. Ideally bug 1 should be fixed before merging since users will most probably try it out, and bug 2 can be easily commented out for now since cross xircuits bugs are troublesome.

Thanks for the review and comment. Finally solved the first bugs which took longer than expected. I agree with you regarding the second bugs as I commented out the command. I tried to solve it but haven't figure it out yet. Will add in the Wishlist.

Also, fixed the name when creating xircuits file via launcher and context menu.

Tested and feels less buggy! Noted the future feature request log, so let's merge this.
