Change of whitespace-mode to whitespace-visual-mode

Hello, I've changed the name and the prefix of my old whitespace-mode package and have also fixed some bugs, which were caused by changes of the XEmacs in the past. The new package can coexist with the package whitespace.el, which is usefull for a different use case. Please exchange the old whitespace-mode.el with the new whitespace-visual-mode.el attached to this email. Regards, Heiko PS: There are other packages in the XEmacs, which I wrote a few years ago, like view-process-mode and hm--html-mode. I've not looked at these packages for a long time. So please let me know, if they should be changed too.
