Bug#760720: qrouter review

Interesting.  After years of nobody mentioning it, I get two requests to
update tkcon.tcl within a few days.

Just note several things:

1)  tkcon.tcl was broken by Tcl version 2.6 and would not scroll through
     the history.  This is probably fixed, but it's best to check.  There's a
     patch for it floating around, if needed.

2)  I used a slightly modified tkcon.tcl, in which at the top I changed "wish"
     to "$(QROUTER_WISH:=wish)" (or something like that).  This is to make
     sure that qrouter runs the version of wish that it was compiled for.  This
     could also be done in the launching shell script, to make sure "wish" is
     aliased to the correct executable.  That would be preferred, as it prevents
     having a modified version of tkcon.tcl.
