Changes to detection of TkTable. TkTable detection was not possible
on FC5 due to the provided tktable package not coming with header
files, and no tktable-devel being offered. Hence static linkage
to Tktable is not possible. Maybe it's not a great idea anyway.
Also modified and updated the DistTar builder for SCons.
Modified SConstruct to allow Tcl/Tk 8.4 to be used.
Modified ascend.spec.in to use system-standard version of Tcl/Tk 8.4.
