Summary: toggle fullscreen and back causes window size changes

Initial Comment:
In certain applications including konquror 0.8.x (qt3), gwenview (qt4), and totem (gtk2), if the application is toggled into full screen and then back, the window size is changed in an apparently random fashion.

This was tested under Debian in two versions of icewm, 1.2.29pre1 and 1.3.4pre2 (Debian builds of both).

Message:
When those apps go fullscreen, they turn off some widgets, thus
decreasing minimum window size. And it seems like icewm can't properly
handle this change for fullscreen windows, so after switching back it
uses "bad" hints.

Working patch attached to debian bug report:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=549896#8

It saves size hints before going fullscreen and restores them back after
leaving fullscreen. I don't know if this is a proper way to handle
this (just spotted this trick in lwm), but it seems to be working fine for
me.

Apply in `src` directory.
Done for icewm 1.2.37-1, applies to icewm_1.2.37+1.3.4pre2-4.

Message:
If window flags changed using wmctrl -i -r $win -b add,fullscreen && wmctrl
-i -r $win -b remove,fullscreen this bug does not appear. Also if window
state changed using hot-key KeyWinFullscreen this bug does not apper too.

Seems that request from application "make my window fullscreen" are
incorrectly interpreted by icewm.
