[ltk-user] PATCH a much better patch that works on 8.4 and 8.5

[Johan Ur Riise]

Here I leave activate-tile on the outside of the with-ltk form in
tile-test. In stead, I have deferred the renaming of widgets, using the
same technique as is used with require-tile, pushing a lambda to the
init hook. Works beautifully with tile-test on  both tcl 8.4 and 8.5,
and also with my own application.

The "unless" in require-tile _could_ be a premature optimization, but it
could also be a hint to the next generation programmers that this is
only for an ancient wish, and could be removed.

So forget my last pathc, but the one adding ttk:: is needed
