This checks that we have Tcl/Tk 8.4 or later, and puts up an error message in a window and quits if not. This was prompted by a patch submitted by Steffen Prohaska, but is done a bit differently (this uses package require rather than looking at [info tclversion], and uses show_error to display the error rather than printing it to stderr).
