* README:
* generic/tk.h: * unix/configure.in: * unix/tk.spec: * win/configure.in: bumped to version 8.3.1 * library/msgbox.tcl (tkMessageBox): changed to use grid in some places, realign icon to anchor nw. * mac/tkMacScale.c: reverted tkMacScale.c to 1.5 equivalent (it was accidentally bumped forward).
