Rewrite connected-lines dragger to not use EDA_ITEM flags.

We had some spurious bugs where both ends would get dragged to a
single point (making them disappear).  While I never caught it
in the debugger, I'm guessing that the flags weren't getting
cleared properly or were getting overwritten or something.  Anyway,
it now uses std::pair instead.
