Revert 124790 - Minimized panels should not open on Windows when activated by the OS

Minimized panels are not "minimized" from the OS point of view so they may receive focus when other windows are minimized or closed. This patch sets the flags on the minimized panels in such way that they are not activated by the OS but still appear in the Alt-Tab menu and on the taskbar.

BUG=102721
TEST=Manually verify that minimized panels do not open spontaneously when other windows are closed, but are accessible through the taskbar and Alt-Tab.
