feature: copy/paste graphics between symbol/schematic editor and footprint/pcb editor

Description

It would be nice if you could copy and paste graphics such as lines and arcs between the symbol editor and footprint editor. And possible also the other editors.

I am making some DSUB components and the DSUB edge shape would save a good amount of time if it could be copied.

Steps to reproduce

1. Mark some graphics in footprint editor
2. ctrl C
3. In symbol editor
4. ctrl V
5. The same shapes appears
