Patch to remember window properties if you change the workspace

Hi,

If you e.g have a sticky window and you maximized-vertically the window
sawfish set unmaximized-geometry (and other properties) to wrong
values if you change the workspace. You can test it:

Open a window and make it sticky. maximized-vertically the window. Open
sawfish-client and "check" the window with: 
"(window-get (select-window) 'swapped)"
go to the next workspace and again:
(window-get (select-window) 'swapped)
go to the next workspace and again:
(window-get (select-window) 'swapped)
and also go back to the workspaces and check again.

We have by all workspace wrong values by "maximized-horizontally" and
"unmaximized-geometry" but not on the first workspace where we have set
the window sticky.

I also read the comments in workspace.jl. The comment before
"(define (swap-out w space)" and in 
"(define (window-add-to-workspace w space)" and also if i read the code
tells me that we should only call "swap-in" in:
"(define (select-workspace* space #!key dont-focus inner-thunk force)"
if we have a copy of the window on a other workspace and not by a
"single window".

I am not sure but i can't believe that that is a features, for me that
is a bug. Please test the patch. Comments welcome.
