Clean and standardize cross-probing action

Between schematic and pcb editors, we want the following actions:

- Single click on ERC/DRC item should show the item in the ERC/DRC
  window.  But if the window is not visible, it should only update the
  status bar
- Double click on ERC/DRC item should show and raid the ERC/DRC window
  as well as select the line item
