git-gui: add horizontal scrollbar to commit buffer

While the commit message widget has a configurable fixed width, it nevertheless allowed to write commit messages which exceeded this limit. Though there is no visual clue, that there is scrolling going on. Now there is a horizontal scrollbar. There seems to be a bug in at least Tcl/Tk up to version 8.6.8, which does not update the horizontal scrollbar if one removes the whole content at once.
