[PD] duplicate connections

[Krzysztof Czaja]

hi Miller,

the possibility to have multiple copies of the same connection
between objects in a patch, i.e. to make a connection [x]_n -> m_[y],
when [x]_n is already connected to m_[y], is left open, both on a gui
level (which means always showing a circle around an inlet), and in
further processing.

I think this should not be allowed, because there is only one visible
line, but the other, `ghost' connections remain active.  So, in case,
you agree, you may look at a simple fix attached.

I have not dealt with `setcursor' branch.  The needed check, quite
similar, would cause some (usually minor) slowdown -- you decide.

Krzysztof

btw, no such duplicates are allowed in max...
