lang/tk-tclX: Remove package due to Tcl upgrade to v8.5

The TclX project is dead.  The homepage still works, but says the main
page for development is <http://www.neosoft.com/TclX/>, and it doesn't
resolve.  Additionally, the last release on Sourceforge was Nov 2005.

TclX does not build with the latest stable version of Tcl.  Rather than
keeping this package on life support, it's prudent to just remove it.

Discussed with wiz@ and he@
